CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims benefit of the priority date of U.S. patent application Ser. No. 60/354,049 filed Jan. 30, 2002, which is incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     This invention is in the field of maize breeding, specifically relating to hybrid maize designated 35D45. 
     BACKGROUND OF THE INVENTION 
     Plant Breeding 
     The goal of plant breeding is to combine in a single variety or hybrid various desirable traits. For field crops, these traits may include resistance to diseases and insects, tolerance to heat and drought, reducing the time to crop maturity, greater yield, and better agronomic quality. With mechanical harvesting of many crops, uniformity of plant characteristics such as germination and stand establishment, growth rate, maturity, and plant and ear height is important. 
     Field crops are bred through techniques that take advantage of the plant&#39;s method of pollination. A plant is self-pollinated if pollen from one flower is transferred to the same or another flower of the same plant. A plant is sib pollinated when individuals within the same family or line are used for pollination. A plant is cross-pollinated if the pollen comes from a flower on a different plant from a different family or line. The term “cross pollination” and “out-cross as used herein do not include self pollination or sib pollination. 
     Plants that have been self-pollinated and selected for type for many generations become homozygous at almost all gene loci and produce a uniform population of true breeding progeny. A cross between two different homozygous lines produces a uniform population of hybrid plants that may be heterozygous for many gene loci. A cross of two plants each heterozygous at a number of gene loci will produce a population of heterogeneous plants that differ genetically and will not be uniform. 
     Maize ( Zea mays  L.), often referred to as corn in the United States, can be bred by both self-pollination and cross-pollination techniques. Maize has separate male and female flowers on the same plant, located on the tassel and the ear, respectively. Natural pollination occurs in maize when wind blows pollen from the tassels to the silks that protrude from the tops of the ears. 
     The development of a hybrid maize variety in a maize plant breeding program involves three steps: (1) the selection of plants from various germplasm pools for initial breeding crosses; (2) the selfing of the selected plants from the breeding crosses for several generations to produce a series of inbred lines, which, individually breed true and are highly uniform; and (3) crossing a selected inbred line with an unrelated inbred line to produce the hybrid progeny (F1). After a sufficient amount of inbreeding successive filial generations will merely serve to increase seed of the developed inbred. Preferably, an inbred line should comprise homozygous alleles at about 95% or more of its loci. 
     During the inbreeding process in maize, the vigor of the lines decreases. Vigor is restored when two different inbred lines are crossed to produce the hybrid progeny (F1). An important consequence of the homozygosity and homogeneity of the inbred lines is that the hybrid created by crossing a defined pair of inbreds will always be the same. Once the inbreds that create a superior hybrid have been identified, a continual supply of the hybrid seed can be produced using these inbred parents and the hybrid corn plants can then be generated from this hybrid seed supply. 
     Large scale commercial maize hybrid production, as it is practiced today, requires the use of some form of male sterility system which controls or inactivates male fertility. A reliable method of controlling male fertility in plants also offers the opportunity for improved plant breeding. This is especially true for development of maize hybrids, which relies upon some sort of male sterility system. There are several ways in which a maize plant can be manipulated so that is male sterile. These include use of manual or mechanical emasculation (or detasseling), cytoplasmic genetic male sterility, nuclear genetic male sterility, gametocides and the like. 
     Hybrid maize seed is often produced by a male sterility system incorporating manual or mechanical detasseling. Alternate strips of two inbred varieties of maize are planted in a field, and the pollen-bearing tassels are removed from one of the inbreds (female) prior to pollen shed. Providing that there is sufficient isolation from sources of foreign maize pollen, the ears of the detasseled inbred will be fertilized only from the other inbred (male), and the resulting seed is therefore hybrid and will form hybrid plants. 
     The laborious detasseling process can be avoided by using cytoplasmic male-sterile (CMS) inbreds. Plants of a CMS inbred are male sterile as a result of factors resulting from the cytoplasmic, as opposed to the nuclear, genome. Thus, this characteristic is inherited exclusively through the female parent in maize plants, since only the female provides cytoplasm to the fertilized seed. CMS plants are fertilized with pollen from another inbred that is not male-sterile. Pollen from the second inbred may or may not contribute genes that make the hybrid plants male-fertile. The same hybrid seed, a portion produced from detasseled fertile maize and a portion produced using the CMS system can be blended to insure that adequate pollen loads are available for fertilization when the hybrid plants are grown. 
     There are several methods of conferring genetic male sterility available, such as multiple mutant genes at separate locations within the genome that confer male sterility, as disclosed in U.S. Pat. Nos. 4,654,465 and 4,727,219 to Brar et al. and chromosomal translocations as described by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. These and all patents referred to are incorporated by reference. In addition to these methods, Albertsen et al., of Pioneer Hi-Bred, U.S. Pat. No. 5,432,068, have developed a system of nuclear male sterility which includes: identifying a gene which is critical to male fertility; silencing this native gene which is critical to male fertility; removing the native promoter from the essential male fertility gene and replacing it with an inducible promoter, inserting this genetically engineered gene back into the plant; and thus creating a plant that is male sterile because the inducible promoter is not “on” resulting in the male fertility gene not being transcribed. Fertility is restored by inducing, or turning “on”, the promoter, which in turn allows the gene that confers male fertility to be transcribed. 
     There are many other methods of conferring genetic male sterility in the art, each with its own benefits and drawbacks. These methods use a variety of approaches such as delivering into the plant a gene encoding a cytotoxic substance associated with a male tissue specific promoter or an antisense system in which a gene critical to fertility is identified and an antisense to that gene is inserted in the plant (see: Fabinjanski, et al. EPO 89/3010153.8 publication no. 329,308 and PCT application PCT/CA90/00037 published as WO 90/08828). 
     Another system useful in controlling male sterility makes use of gametocides. Gametocides are not a genetic system, but rather a topical application of chemicals. These chemicals affect cells that are critical to male fertility. The application of these chemicals affects fertility in the plants only for the growing season in which the gametocide is applied (see Carlson, Glenn R., U.S. Pat. No. 4,936,904). Application of the gametocide, timing of the application and genotype specificity often limit the usefulness of the approach and it is not appropriate in all situations. 
     The use of male sterile inbreds is but one factor in the production of maize hybrids. The development of maize hybrids in a maize plant breeding program requires, in general, the development of homozygous inbred lines, the crossing of these lines, and the evaluation of the crosses. Maize plant breeding, programs combine the genetic backgrounds from two or more inbred lines or various other germplasm sources into breeding populations from which new inbred lines are developed by selfing and selection of desired phenotypes. Hybrids also can be used as a source of plant breeding material or as source populations from which to develop or derive new maize lines. Plant breeding techniques known in the art and used in a maize plant breeding program include, but are not limited to, recurrent selection, backcrossing, double haploids, pedigree breeding, restriction fragment length polymorphism enhanced selection, genetic marker enhanced selection, and transformation. Often a combination of these techniques are used. The inbred lines derived from hybrids can be developed using plant breeding techniques as described above. New inbreds are crossed with other inbred lines and the hybrids from these crosses are evaluated to determine which of those have commercial potential. 
     Backcrossing can be used to improve inbred lines and a hybrid which is made using those inbreds. Backcrossing can be used to transfer a specific desirable trait from one line, the donor parent, to an inbred called the recurrent parent which has overall good agronomic characteristics yet that lacks the desirable trait. This transfer of the desirable trait into an inbred with overall good agronomic characteristics can be accomplished by first crossing a recurrent parent to a donor parent (non-recurrent parent). The progeny of this cross is then mated back to the recurrent parent followed by selection in the resultant progeny for the desired trait to be transferred from the non-recurrent parent. Typically after four or more backcross generations with selection for the desired trait, the progeny will contain essentially all genes of the recurrent parent except for the genes controlling the desired trait. But the number of backcross generations can be less if molecular markers are used during the selection or elite germplasm is used as the donor parent. The last backcross generation is then selfed to give pure breeding progeny for the gene(s) being transferred. 
     Backcrossing can also be used in conjunction with pedigree breeding to develop new inbred lines. For example, an F1 can be created that is backcrossed to one of its parent lines to create a BC1. Progeny are selfed and selected so that the newly developed inbred has many of the attributes of the recurrent parent and some of the desired attributes of the non-recurrent parent. 
     Recurrent selection is a method used in a plant breeding program to improve a population of plants. The method entails individual plants cross pollinating with each other to form progeny which are then grown. The superior progeny are then selected by any number of methods, which include individual plant, half sib progeny, full sib progeny, selfed progeny and topcrossing. The selected progeny are cross pollinated with each other to form progeny for another population. This population is planted and again superior plants are selected to cross pollinate with each other. Recurrent selection is a cyclical process and therefore can be repeated as many times as desired. The objective of recurrent selection is to improve the traits of a population. The improved population can then be used as a source of breeding material to obtain inbred lines to be used in hybrids or used as parents for a synthetic cultivar. A synthetic cultivar is the resultant progeny formed by the intercrossing of several selected inbreds. Mass selection is a useful technique when used in conjunction with molecular marker enhanced selection. 
     Molecular markers including techniques such as Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction (APPCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), Single Nucleotide Polymorphisms (SNPs) and Simple Sequence Repeats (SSRS) may be used in plant breeding methods. One use of molecular markers is Quantitative Trait Loci (QTL) mapping. QYL mapping is the use of markers, which are closely linked to alleles that have measurable effects on a quantitative trait. Selection in the breeding process is based upon the accumulation of markers linked to the positive effecting alleles and/or the elimination of the markers linked to the negative effecting alleles from the plant&#39;s genome. 
     Molecular markers can also be used during the breeding process for the selection of qualitative traits. For example, markers closely linked to alleles or markers containing sequences within the actual alleles of interest can be used to select plants that contain the alleles of interest during a backcrossing breeding program. The markers can also be used to select for the genome of the recurrent parent and against the markers of the donor parent. Using this procedure can minimize the amount of genome from the donor parent that remains in the selected plants. It can also be used to reduce the number of crosses back to the recurrent parent needed in a backcrossing program. The use of molecular markers in the selection process is often called Genetic Marker Enhanced Selection. 
     The production of double haploids can also be used for the development of inbreds in a breeding program. Double haploids are produced by the doubling of a set of chromosomes (1N) from a heterozygous plant to produce a completely homozygous individual. For example, see Wan et al., “Efficient Production of Doubled Haploid Plants Through Colchicine Treatment of Anther-Derived Maize Callus”, Theoretical and Applied Genetics, 77:889-892, 1989 This can be advantageous because the process can eliminate the generations of selfing needed to obtain a homozygous plant from a heterozygous source. 
     Hybrid seed production requires elimination or inactivation of pollen produced by the female parent. Incomplete removal or inactivation of the pollen provides the potential for self-pollination. This inadvertently self-pollinated seed may be unintentionally harvested and packaged with hybrid seed. Also, because the male parent is grown next to the female parent in the field there is the very low probability that the male selfed seed could be unintentionally harvested and packaged with the hybrid seed. Once the seed from the hybrid bag is planted, it is possible to identify and select these self-pollinated plants. These self-pollinated plants will be genetically equivalent to one of the inbred lines used to produce the hybrid. Though the possibility of inbreds being included hybrid seed bags exists, the occurrence is very low because much care is taken to avoid such inclusions. It is worth noting that hybrid seed is sold to growers for the production of grain and forage and not for breeding or seed production. 
     By an individual skilled in plant breeding, these inbred plants unintentionally included in commercial hybrid seed can be identified and selected due to their decreased vigor when compared to the hybrid. Inbreds are identified by their less vigorous appearance for vegetative and/or reproductive characteristics, including shorter plant height, small ear size, ear and kernel shape, cob color, or other characteristics. 
     Identification of these self-pollinated lines can also be accomplished through molecular marker analyses. See, “The Identification of Female Selfs in Hybrid Maize: A Comparison Using Electrophoresis and Morphology”, Smith, J. S. C. and Wych, R. D., Seed Science and Technology 14, pp. 1-8 (1995), the disclosure of which is expressly incorporated herein by reference. Through these technologies, the homozygosity of the self pollinated line can be verified by analyzing allelic composition at various loci along the genome. Those methods allow for rapid identification of the invention disclosed herein. See also, “Identification of Atypical Plants in Hybrid Maize Seed by Postcontrol and Electrophoresis” Sarca, V. et al., Probleme de Genetica Teoritica si Aplicata Vol. 20(1) p. 2942. 
     Another form of commercial hybrid production involves the use of a mixture of male sterile hybrid seed and male pollinator seed. When planted, the resulting male sterile hybrid plants are pollinated by the pollinator plants. This method is primarily used to produce grain with enhanced quality grain traits, such as high oil, because desired quality grain traits expressed in the pollinator will also be expressed in the grain produced on the male sterile hybrid plant. In this method the desired quality grain trait does not have to be incorporated by lengthy procedures such as recurrent backcross selection into an inbred parent line. One use of this method is described U.S. Pat. Nos. 5,704,160 and 5,706,603. 
     There are many important factors to be considered in the art of plant breeding, such as the ability to recognize important morphological and, physiological characteristics, the ability to design evaluation techniques for genotypic and phenotypic traits of interest, and the abtlity to search out and exploit the genes for the desired traits in new or improved combinations. 
     The objective of commercial maize hybrid line development resulting from a maize plant breeding program is to develop new inbred lines to produce hybrids that combine to produce high grain yields and superior agronomic performance. One of the primary traits breeders seek is yield. However, many other major agronomic traits are of importance in hybrid combination and have an impact on yield or otherwise provide superior performance in hybrid combinations. Such traits include percent grain moisture at harvest, relative maturity, resistance to stalk breakage, resistance to root lodging, grain quality, and disease and insect resistance. In addition, the lines per se must have acceptable performance for parental traits such as seed yields, kernel sizes, pollen production, all of which affect ability to provide parental lines in sufficient quantity and quality for hybridization. These traits have been shown to be under genetic control and many if not all of the traits are affected by multiple genes. 
     Pedigree Breeding 
     The pedigree method of breeding is the mostly widely used methodology for new hybrid line development. 
     In general terms this procedure consists of crossing two inbred lines to produce the non-segregating F1 generation, and self pollination of the F1 generation to produce the F2 generation that segregates for all factors for which the inbred parents differ. An example of this process is set forth below. Variations of this generalized pedigree method are used, but all these variations produce a segregating generation which contains a range of variation for the traits of interest. 
    
    
     EXAMPLE 1 
     Hypothetical Example of Pedigree Breeding Program 
     Consider a cross between two inbred lines that differ for alleles at six loci. 
     The parental genotypes are: 
     
         
         
           
             Parent1 A b C d e F/A b C d e F 
             Parent2 a B c D E f/a B c D E f
 
the F1 from a cross between these two parents is:
 
             F1 A b C d e F/a B c D E f
 
Selfing F1 will produce an F2 generation including the following genotypes:
 
             A B c D E f/a b C d e F 
             A B c D e f/a b C d E F 
             A B c D e f/a b C d e F
           .   .   .   
         
           
         
       
    
     The number of genotypes in the F2 is 3 6  for six segregating loci (729) and will produce (2 6 )−2 possible new inbreds, (62 for six segregating loci). 
     Each inbred parent which is used in breeding crosses represents a unique combination of genes, and the combined effects of the genes define the performance of the inbred and its performance in hybrid combination. There is published evidence (Smith, O. S., J. S. C. Smith, S. L. Bowen, R. A. Tenborg and S. J. Wall,  TAG  80:833-840 (1990)) that each of the lines are different and can be uniquely identified on the basis of genetically-controlled molecular markers. 
     It has been shown (Hallauer, Amel R. and Miranda, J. B. Fo. Quantitative  Genetics in Maize Breeding , Iowa State University Press, Ames Iowa, 1981) that most traits of economic value in maize are under the genetic control of multiple genetic loci, and that there are a large number of unique combinations of these genes present in elite maize germplasm. If not, genetic progress using elite inbred lines would no longer be possible. Studies by Duvick and Russell (Duvick, D. N.,  Maydica  37:69-79, (1992); Russell, W. A.,  Maydica  XXIX:375-390 (1983)) have shown that over the last 50 years the rate of genetic progress in commercial hybrids has been between one and two percent per year. 
     The number of genes affecting the trait of primary economic importance in maize, grain yield, has been estimated to be in the range of 10-1000. Inbred lines which are used as parents for breeding crosses differ in the number and combination of these genes. These factors make the plant breeder&#39;s task more difficult. Compounding this is evidence that no one line contains the favorable allele at all loci, and that different alleles have different economic values depending on the genetic background and field environment in which the hybrid is grown. Fifty years of breeding experience suggests that there are many genes affecting grain yield and each of these has a relatively small effect on this trait. The effects are small compared to breeders&#39; ability to measure grain yield differences in evaluation trials. Therefore, the parents of the breeding cross must differ at several of these loci so that the genetic differences in the progeny will be large enough that breeders can develop a line that increases the economic worth of its hybrids over that of hybrids made with either parent. 
     If the number of loci segregating in a cross between two inbred lines is n, the number of unique genotypes in the F2 generation is 3 n  and the number of unique inbred lines from this cross is {(2 n )−2}. Only a very limited number of these combinations is commercially useful. 
     By way of example, if it is assumed that the number of segregating loci in F2 is somewhere between 20 and 50, and that each parent is fixed for half the favorable alleles, it is then possible to calculate the approximate probabilities of finding an inbred that has the favorable allele at {(n/2)+m} loci, where n/2 is the number of favorable alleles in each of the parents and m is the number of additional favorable alleles in the new inbred. See Example 2 below. The number m is assumed to be greater than three because each allele has so small an effect that evaluation techniques are not sensitive enough to detect differences due to three or less favorable alleles. The probabilities in Example 2 are on the order of 10 −5  or smaller and they are the probabilities that at least one genotype with (n/2)=m favorable alleles will exist. 
     To put this in perspective, the number of plants grown on 60 million acres (approximate United States corn acreage) at 25,000 plants/acre is 1.5×10 12 . 
     EXAMPLE 2 
     Probability of Finding an Inbred with m of n Favorable Alleles. 
     Assume each parent has n/2 of the favorable alleles and only ½ of the combinations of loci are economically useful.

     The possibility of having a usably high probability of being able to identify this genotype based on replicated field testing would be most likely smaller than this, and is a function of how large a population of genotypes is tested and how testing resources are allocated in the testing program. 
     A breeder uses various methods to help determine which plants should be selected from the segregating populations and ultimately which inbred lines will be used to develop hybrids for commercialization. In addition to the knowledge of the germplasm and other skills the breeder uses, a part of the selection process is dependent on experimental design coupled with the use of statistical analysis. Experimental design and statistical analysis are used to help determine which plants, which family of plants, and finally which inbred lines and hybrid combinations are significantly better or different for one or more traits of interest. Experimental design methods are used to asses error so that differences between two inbred lines or two hybrid lines can be more accurately determined. Statistical analysis includes the calculation of mean values, determination of the statistical significance of the sources of variation, and the calculation of the appropriate variance components. Either a five or one percent significance level is customarily used to determine whether a difference that occurs for a given trait is real or due to the environment or experimental error. One of ordinary skill in the art of plant breeding would know how to evaluate the traits of two plant varieties to determine if there is no significant difference between the two traits expressed by those varieties. For example, see Fehr, Walt, Principles of Cultivar Development, p. 261-286 (1987) which is incorporated herein by reference. Mean trait values may be used to determine whether trait differences are significant, and preferably the traits are measured on plants grown under the same environmental conditions. Combining ability of a line, as well as the performance of the line per se, is a factor in the selection of improved maize inbreds. Combining ability refers to a line&#39;s contribution as a parent when crossed with other lines to form hybrids. The hybrids formed for the purpose of selecting superior lines are designated test crosses. One way of measuring combining ability is by using breeding values. Breeding values are based in part on the overall mean of a number of test crosses. This mean is then adjusted to remove environmental effects and it is adjusted for known genetic relationships among the lines. 
     Once such a line is developed its value to society is substantial since it is important to advance the germplasm base as a whole in order to maintain or improve traits such as yield, disease resistance, pest resistance and plant performance in extreme weather conditions. 
     SUMMARY OF THE INVENTION 
     According to the invention, there is provided a hybrid maize plant, designated as 35D45, produced by crossing two Pioneer Hi-Bred International, Inc. proprietary inbred maize lines GE533003 and GE616672. These lines, deposited with the American Type Culture Collection, (ATCC), Manassas, Va. 20110, have Accession No. PTA-5504 for GE533003 and Accession No. PTA-5534 for GE616672. This invention thus relates to the hybrid seed 35D45, the hybrid plant and its parts produced from the seed, and variants, mutants and trivial modifications of hybrid 35D45. This invention also relates to methods for producing a maize plant containing in its genetic material one or more transgenes and to the transgenic maize plants and their parts produced by that method. This invention further relates to methods for producing maize lines derived from hybrid maize line 35D45 and to the maize lines derived by the use of those methods. This hybrid maize plant is characterized by unique genetics with a stable yield and a good package of agronomic traits.

     DETAILED DESCRIPTION OF THE INVENTION 
     Inbred maize lines are typically developed for use in the production of hybrid maize lines. Maize hybrids need to be highly homogeneous, heterozygous and reproducible to be useful as commercial hybrids. There are many analytical methods available to determine the heterozygous nature and the identity of these lines. 
     The oldest and most traditional method of analysis is the observation of phenotypic traits. The data is usually collected in field experiments over the life of the maize plants to be examined. Phenotypic characteristics most often observed are for traits associated with plant morphology, ear and kernel morphology, insect and disease resistance, maturity, and yield. 
     In addition to phenotypic observations, the genotype of a plant can also be examined. A plant&#39;s genotype can be used to identify plants of the same variety or a related variety. For example, the genotype can be used to determine the pedigree of a plant. There are many laboratory-based techniques available for the analysis, comparison and characterization of plant genotype; among these are Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polyrnerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats (SSRs) which are also referred to as Microsatellites, and Single Nucleotide Polymorphisms (SNPs). 
     Isozyme Electrophoresis and RFLPs as discussed in Lee, M., “Inbred Lines of Maize and Their Molecular Markers,”  The Maize Handbook , (Springer-Verlag, New York, Inc. 1994, at 423-432) incorporated herein by reference, have been widely used to determine genetic composition. Isozyme Electrophoresis has a relatively low number of available markers and a low number of allelic variants. 
     RFLPs allow more discrimination because they have a higher degree of allelic variation in maize and a larger number of markers can be found. Both of these methods have been eclipsed by SSRs as discussed in Smith et al., “An evaluation of the utility of SSR loci as molecular markers in maize ( Zea mays L. ): comparisons with data from RFLPs and pedigree”,  Theoretical and Applied Genetics  (1997) vol. 95 at 163-173 and by Pejic et al., “Comparative analysis of genetic similarity among maize inbreds detected by RFLPs, RAPDs, SSRs, and AFLPs,”  Theoretical and Applied Genetcs  (1998) at 1248-1255 incorporated herein by reference. SSR technology is more efficient and practical to use than RFLPs; more marker loci can be routinely used and more alleles per marker locus can be found using SSRs in comparison to RFLPs. Single Nucleotide Polymorphisms may also be used to identify the unique genetic composition of the invention and progeny lines retaining that unique genetic composition. Various molecular marker techniques may be used in combination to enhance overall resolution. 
     Maize DNA molecular marker linkage maps have been rapidly constructed and widely implemented in genetic studies. One such study is described in Boppenmaier, et al., “Comparisons among strains of inbreds for RFLPs”, Maize Genetics Cooperative Newsletter, 65:1991, pg. 90, is incorporated herein by reference.

The hybrid is particularly suited to the Central Corn Belt, Northwest, Northcentral, Western and Drylands regions of the United States. 
     Pioneer Brand Hybrid 35D45 is a single cross, yellow endosperrn, dent maize hybrid. Hybrid 35D45 has a relative maturity of approximately 104 based on the Comparative Relative Maturity Rating System for harvest moisture of grain.

     Research Comparisons for Pioneer Hybrid 35D45 
     Comparisons of characteristics for Pioneer Brand Hybrid 35D45 were made against Pioneer Brand Hybrids 34G81, 35P12, and 36B08. 
     Table 2A compares hybrid 35D45 with 34G81, a hybrid with solid agronomic traits. The table indicates that hybrid 35D45 is significantly higher yielding with a significantly higher test weight than hybrid 34G81, Hybrid 35D45 further demonstrates significantly superior resistance to artificial brittle snap and a significantly taller plant stature than hybrid 34G81. The 35D45 hybrid further provides significantly better tolerance to Gray Leaf Spot and to Gibberella Ear Rot (GIBERS SCORE ABS) than hybrid 34G81. 
     Table 2B compares hybrid 35D45 with hybrid 35P12, hybrid with a solid package of agronomic traits and similar maturity. The results indicate that the hybrids are similar in yield, but hybrid 35D45 has a significantly higher test weight than hybrid 35P12. Hybrid 35D45 also has a significantly higher number of growing degree units to pollen shed and to silk than hybrid 35P12. Hybrid 35D45 demonstrates a significantly taller plant stature as well as significantly superior resistance to late season stalk lodging than hybrid 35P12. Hybrid 35D45 further demonstrates significantly superior stay green and significantly better tolerance to Gray Leaf Spot and to Gibberella Ear Rot (GIBERS SCORE ABS) than hybrid 35P12. 
     Table 2C compares hybrid 35D45 with hybrid 36B08, hybrid with a solid package of agronomic traits. The results indicate that hybrid 35D45 is significantly higher yielding (BU/A ABS and BU/A % MN) with significantly a significantly higher test weight than hybrid 36B08. Hybrid 35D45 also is later to mature with a significantly higher number of growing degree units to pollen shed and to silk than hybrid 36B08. Hybrid 35D45 further demonstrates significantly superior stay green, significantly taller plant stature and significantly better tolerance to artificial brittle snap than hybrid 36B08.

     Further Embodiments of the Invention 
     This invention also is directed to methods for producing a maize plant by crossing a first parent maize plant with a second parent maize plant wherein either the first or second parent maize plant is Pioneer Brand hybrid 35D45. In one embodiment the parent hybrid maize plant 35D45 will be crossed with another maize plant, sibbed, or selfed, to generate an inbred which may be used in the development of additional plants. In another embodiment, double haploid methods may be used to generate an inbred plant. Further, this invention is directed to methods for producing a hybrid 35D45-progeny maize plant by crossing hybrid maize plant 35D45 with itself or a second maize plant and growing the progeny seed, and repeating the crossing and growing steps with the hybrid maize 35D45-progeny plant from 1 to 2 times, 1 to 3 times, 1 to 4 times, or 1 to 5 times. Thus, any such methods using the hybrid maize plant 35D45 are part of this invention: selfing, sibbing, backcrosses, hybrid production, crosses to populations, and the like. 
     All plants produced using hybrid maize plant 35D45 as a parent are within the scope of this invention, including plants derived from hybrid maize plant 35D45. This includes varieties essentially derived from variety 35D45 with the term “essentially derived variety” having the meaning ascribed to such term in 7 U.S.C. § 2104(a)(3) of the Plant Variety Protection Act, which definition is hereby incorporated by reference. This also includes progeny plant and parts thereof with at least one ancestor that is hybrid maize plant 35D45 and more specifically where the pedigree of this progeny includes 1, 2, 3, 4, and/or 5 or cross pollinations to a maize plant 35D45, or a plant that has 35D45 as a progenitor. All breeders of ordinary skill in the art maintain pedigree records of their breeding programs. These pedigree records contain a detailed description of the breeding process, including a listing of all parental lines used in the breeding process and information on how such line was used. Thus, a breeder would know if 35D45 were used in the development of a progeny line, and would also know how many cross-pollinations to a line other than 35D45 were made in the development of any progeny line. A progeny line so developed may then be used in crosses with other, different, maize inbreds to produce first generation (F 1 ) maize hybrid seeds and plants with superior characteristics. 
     Specific methods and products produced using hybrid maize plant in plant breeding are encompassed within the scope of the invention listed above. One such embodiment is the method of crossing hybrid maize plant 35D45 with itself to form a homozygous inbred parent line. Hybrid 35D45 would be sib or self pollinated to form a population of progeny plants. The population of progeny plants produced by this method is also an embodiment of the invention. This first population of progeny plants will have received all of its alleles from hybrid maize plant 35D45. The inbreeding process results in homozygous loci being generated and is repeated until the plant is homozygous at substantially every loci and becomes an inbred line. Once this is accomplished the inbred line may be used in crosses with other inbred lines, including but not limited to inbred parent lines disclosed herein to generate a first generation of F1 hybrid plants. One of ordinary skill in the art can utilize breeder notebooks, or molecular methods to identify a particular hybrid plant produced using an inbred line derived from maize hybrid plant 35D45, in addition to comparing traits. Any such individual inbred plant is also encompassed by this invention. 
     These embodiments also include use of these methods with transgenic or single gene conversions of maize hybrid plant 35D45. Another such embodiment is a method of developing a line genetically similar to hybrid maize plant 35D45 in breeding that involves the repeated backcrossing of an inbred parent of, or an inbred line derived from, hybrid maize plant 35D45 to another different maize plant any number of times. Using backcrossing methods, or even the tissue culture and transgenic methods described herein, the single gene conversion methods described herein, or other breeding methods known to one of ordinary skill in the art, one can develop individual plants, plant cells, and populations of plants that retain at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 99.5% genetic similarity or identity to maize hybrid plant 35D45. The percentage of the genetics retained in the progeny may be measured by either pedigree analysis or through the use of genetic techniques such as molecular markers or electrophoresis. In pedigree analysis, on average 50% of the starting germplasm would be passed to the progeny line after one cross to a different line, 25% after another cross to a different line, and so on. Molecular markers could also be used to confirm and/or determine the pedigree of the progeny line. The inbred parent would then be crossed to a second inbred parent of or derived from hybrid maize plant 35D45 to create hybrid maize plant 35D45 with additional beneficial traits such as transgenes or single gene conversions. 
     One method for producing a line derived from hybrid maize plant is as follows. One of ordinary skill in the art would obtain hybrid maize plant 35D45 and cross it with another variety of maize, such as an elite inbred variety. The F1 seed derived from this cross would be grown to form a population. The nuclear genome of the F1 would be made-up of 50% of hybrid maize plant 35D45 and 50% of the other elite variety. The F1 seed would be grown and allowed to self, thereby forming F2 seed. On average the F2 seed nuclear genome would have derived 50% of its alleles from the parent hybrid plant 35D45 and 50% from the other maize variety, but various individual plants from the population would have a much greater percentage of their alleles derived from the parent maize hybrid plant (Wang J. and R. Bernardo, 2000, Crop Sci. 40:659-665 and Bemardo, R. and A. L. Kahler, 2001, Theor. Appl. Genet 102:986-992). Molecular markers of 35D45, or its parents identified from routine screening of the deposited samples herein could be used to select and retain those lines with high similarity to 35D45. The F2 seed would be grown and selection of plants would be made based on visual observation, markers and/or measurement of traits. The traits used for selection may be any 35D45 trait described in this specification, including the hybrid maize plant 35D45 traits of good drought tolerance, above average test weight, stable yield, and particularly suited to the Central Corn Belt, Northwest, Northcentral, Western and Drylands regions of the United States. 
     Such traits may also be the good general or specific combining ability of 35D45, including its ability to produce single gene conversions, or other hybrids. The 35D45 progeny plants that exhibit one or more of the desired 35D45 traits, such as those listed above, would be selected and each plant would be harvested separately. This F3 seed from each plant would be grown in individual rows and allowed to self. Then selected rows or plants from the rows would be harvested individually. The selections would again be based on visual observation, markers and/or measurements for desirable traits of the plants, such as one or more of the desirable 35D45 traits listed above. 
     The process of growing and selection would be repeated any number of times until a 35D45 progeny plant is obtained. The 35D45 progeny inbred plant would contain desirable traits in hybrid combination derived from hybrid plant 35D45. The resulting progeny line would benefit from the efforts of the inventor(s), and would not have existed but for the inventor(s) work in creating 35D45. Another embodiment of the invention is a 35D45 progeny plant that has received the desirable 35D45 traits listed above through the use of 35D45, which traits were not exhibited by other plants used in the breeding process. 
     The previous example can be modified in numerous ways, for instance selection may or may not occur at every selfing generation, the hybrid may immediately be selfed without crossing to another plant, selection may occur before or after the actual self-pollination process occurs, or individual selections may be made by harvesting individual ears, plants, rows or plots at any point during the breeding process described. In addition, double haploid breeding methods may be used at any step in the process. The population of plants produced at each and any cycle of breeding is also an embodiment of the invention. In each case the use of 35D45 provides a substantial benefit. The linkage groups of 35D45 would be retained in the progeny lines, and since current estimates of the maize genome size is about 50,000-80,000 genes (Xiaowu, Gai et al., Nudeic Acids Research, 2000, Vol. 28, No. 1, 94-96), in addition to a large amount of non-coding DNA that impacts gene expression, it provides a significant advantage to use 35D45 as starting material to produce a line that retains desired genetics or traits of 35D45. 
     Another embodiment of this invention is the method of obtaining a substantially homozygous 35D45 progeny plant by obtaining a seed from the cross of 35D45 and another maize plant and applying double haploid methods to the F1 seed or F1 plant or to any successive filial generation. Such methods substantially decrease the number of generations required to produce an inbred with similar genetics or characteristics to 35D45. 
     A further embodiment of the invention is a single gene conversion of 35D45 obtained by crossing inbred parent plants of hybrid maize plant 35D45, which comprise the single gene conversion. For a dominant or additive trait at least one of the inbred parents would include single gene conversion in its genome. For a recessive trait, each parent would include the single gene conversion in its genome. in each case the resultant hybrid maize plant 35D45 obtained from the cross of the parents includes a single gene conversion or transgene. A single gene conversion occurs when DNA sequences are introduced through traditional (non-transformation) breeding techniques, such as backcrossing (Hallauer et al, 1988). DNA sequences, whether naturally occurring or transgenes, may be introduced using these traditional breeding techniques. The term single gene conversion is also referred to in the art as a single locus conversion. Reference is made to US 2002/0062506A1 for a detailed discussion of single locus conversions and traits that may be incorporated into 35D45 through single gene conversion. 
     Desired traits transferred through this process include, but are not limited to, waxy starch, nutritional enhancements, industrial enhancements, disease resistance, insect resistance, herbicide resistance and yield enhancements. The trait of interest is transferred from the donor parent to the recurrent parent, in this case, an inbred parent of the maize plant disclosed herein. Single gene traits may result from either the transfer of a dominant allele or a recessive allele. Selection of progeny containing the trait of interest is done by direct selection for a trait associated with a dominant allele. Selection of progeny for a trait that is transferred via a recessive allele, such as the waxy starch characteristic, requires growing and selfing the first backcross to determine which plants carry the recessive alleles. Recessive traits may require additional progeny testing in successive backcross generations to determine the presence of the gene of interest. Along with selection for the trait of interest, progeny are selected for the phenotype of the recurrent parent. It should be understood that occasionally additional polynucleotide sequences or genes are transferred along with the single gene conversion trait of interest. A progeny comprising at least 98%, 99%, 99.5% and 99.9% genetic identity to the recurrent parent, the maize line disclosed herein, comprising the single gene conversion trait or traits of interest, is considered to be a single gene conversion of hybrid 35D45. 
     It should be understood that the plant can, through routine manipulation by detasseling, cytoplasmic genes, nuclear genes, or other factors, be produced in a male-sterile form. The term manipulated to be male sterile refers to the use of any available techniques to produce a male sterile version of maize line 35D45. The male sterility may be either partial or complete male sterility. 
     Such embodiments are also within the scope of the present claims. This invention includes hybrid maize seed of 35D45 and the hybrid maize plant produced therefrom. The foregoing was set forth by way of example and is not intended to limit the scope of the invention. 
     This invention is also directed to the use of hybrid maize plant 35D45 in tissue culture. As used herein, the term plant includes plant protoplasts, plant cell tissue cultures from which maize plants can be regenerated, plant calli, plant dumps, and plant cells that are intact in plants, or parts of plants, such as embryos, pollen, ovules, flowers, kernels, ears, cobs, leaves, seeds, husks, stalks, roots, root tips, anthers, silk and the like. As used herein the phrase “growing the seed” or “grown from the seed” includes embryo rescue, isolation of cells from seed for use in tissue culture, as well as traditional growing methods. 
     Duncan, Williams, Zehr, and Widholm,  Planta , (1985) 165:322-332 reflects that 97% of the plants cultured which produced callus were capable of plant regeneration. Subsequent experiments with both inbreds and hybrids produced 91% regenerable callus which produced plants. In a further study in 1988, Songstad, Duncan &amp; Widholm in Plant Cell Reports (1988), 7:262-265 reports several media additions which enhance regenerability of callus of two inbred lines. Other published reports also indicated that “nontraditional” tissues are capable of producing somatic embryogenesis and plant regeneration. K. P. Rao, et al.,  Maize Genetics Cooperation Newsletter , 60:64-65 (1986), refers to somatic embryogenesis from glume callus cultures and B. V. Conger, et al.,  Plant Cell Reports , 6:345-347 (1987) indicates somatic embryogenesis from the tissue cultures of maize leaf segments. Thus, it is clear from the literature that the state of the art is such that these methods of obtaining plants are, and were, “conventional” in the sense that they are routinely used and have a very high rate of success. 
     Tissue culture of maize is described in European Patent Application, publication 160,390, incorporated herein by reference. Maize tissue culture procedures are also described in Green and Rhodes, “Plant Regeneration in Tissue Culture of Maize,”  Maize for Biological Research  (Plant Molecular Biology Association, Charlottesville, Va. 1982, at 367-372) and in Duncan, et al., “The Production of Callus Capable of Plant Regeneration from Immature Embryos of Numerous  Zae Mays  Genotypes,” 165  Planta  322-332 (1985). Thus, another aspect of this invention is to provide cells which upon growth and differentiation produce maize plants having the genotype andlor physiological and morphological characteristics of hybrid maize plant 35D45. 
     The utility of hybrid maize plant 35D45 also extends to crosses with other species. Commonly, suitable species will be of the family Graminaceae, and especially of the genera  Zea, Tripsacum, Coix, Schlerachne, Polytoca, Chionachne, and Trilobachne , of the tribe Maydeae. Potentially suitable for crosses with 35D45 may be the various varieties of grain sorghum,  Sorghum, bicolor  (L.) Moench. 
     Transformation of Maize 
     The advent of new molecular biological techniques have allowed the isolation and characterization of genetic elements with specific functions, such as encoding specific protein products. Scientists in the field of plant biology developed a strong interest in engineering the genome of plants to contain and express foreign genetic elements, or additional, or modified versions of native or endogenous genetic elements in order to alter the traits of a plant in a specific manner. Any DNA sequence, whether from a different species or from the same species, that are inserted into the genome using transformation are referred to herein collectively as “transgenes”. Over the last fifteen to twenty years several methods for producing transgenic plants have been developed, and the present invention, in particular embodiments, also relates to transformed versions of the claimed hybrid maize plant 35D45. 
     Numerous methods for plant transformation have been developed, including biological and physical, plant transformation protocols. See, for example, Miki et al., “Procedures for Introducing Foreign DNA into Plants” in  Methods in Plant Molecular Biology and Biotechnology , Glick, B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages 67-88 and Armstrong, “The First Decade of Maize Transformation: A Review and Future Perspective” (Maydica 44:101-109, 1999). In addition, expression vectors and in vitro culture methods for plant cell or tissue transformation and regeneration of plants are available. See, for example, Gruber et al., “Vectors for Plant Transformation” in  Methods in Plant Molecular Biology and Biotechnology , Glick, B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages 89-119. See U.S. Pat. No. 6,118,055, which is herein incorporated by reference. 
     The most prevalent types of plant transformation involve the construction of an expression vector. Such a vector comprises a DNA sequence that contains a gene under the control of or operatively linked to a regulatory element, for example a promoter. The vector may contain one or more genes and one or more regulatory elements. 
     A genetic trait which has been engineered into a particular parent maize plant using transformation techniques, could be moved into another line using traditional breeding techniques that are well known in the plant breeding arts. These lines can then be crossed to generate a hybrid maize plant such as hybrid maize plant 35D45 which comprises a transgene. For example, a backcrossing approach could be used to move a transgene from a transformed maize plant to an elite inbred line and the resulting progeny would comprise a transgene. Also, if an inbred line was used for the transformation then the transgenic plants could be crossed to a different inbred in order to produce a transgenic hybrid maize plant. As used herein, “crossing” can refer to a simple X by Y cross, or the process of backcrossing, depending on the context. 
     Various genetic elements can be introduced into the plant genome using transformation. These elements include but are not limited to genes; coding sequences; inducible, constitutive, and tissue specific promoters; enhancing sequences; and signal and targeting sequences. See U.S. Pat. No. 6,284,953, which is herein incorporated by reference. 
     With transgenic plants according to the present invention, a foreign protein can be produced in commercial quantities. Thus, techniques for the selection and propagation of transformed plants, which are well understood in the art, yield a plurality of transgenic plants which are harvested in a conventional manner, and a foreign protein then can be extracted from a tissue of interest or from total biomass. Protein extraction from plant biomass can be accomplished by known methods which are discussed, for example, by Heney and Orr,  Anal. Biochem . 114: 92-6 (1981). 
     According to a preferred embodiment, the transgenic plant provided for commercial production of foreign protein is maize. In another preferred embodiment, the biomass of interest is seed. A genetic map can be generated, primarily via conventional Restriction Fragment Length Polymorphisms (RFLP), Polymerase Chain Reaction (PCR) analysis, Simple Sequence Repeats (SSR) and Single Nucleotide Polymorphisms (SNP) which identifies the approximate chromosomal location of the integrated DNA molecule. For exemplary methodologies in this regard, see Glick and Thompson, METHODS IN PLANT MOLECULAR BIOLOGY AND BIOTECHNOLOGY 269-284 (CRC Press, Boca Raton,1993). Map information concerning chromosomal location is useful for proprietary protection of a subject transgenic plant. If unauthorized propagation is undertaken and crosses made with other germplasm, the map of the integration region can be compared to similar maps for suspect plants, to determine if the latter have a common parentage with the subject plant. Map comparisons would involve hybridizations, RFLP, PCR, SSR and sequencing, all of which are conventional techniques. 
     Likewise, by means of the present invention, plants can be genetically engineered to express various phenotypes of agronomic interest. Through the transformation of maize the expression of genes can be modulated to enhance disease resistance, insect resistance, herbicide resistance, agronomic traits as well as grain quality traits. Transformation can also be used to insert DNA sequences which control or help control male-sterility. DNA sequences native to maize as well as non-native DNA sequences can be transformed into maize and used to modulate levels of native or non-native proteins. Anti-sense technology, various promoters, targeting sequences, enhancing sequences, and other DNA sequences can be inserted into the maize genome for the purpose of modulating the expression of proteins. Exemplary transgenes implicated in this regard include, but are not limited to, those categorized below. 
     1. Transgenes that Confer Resistance to Pests or Disease and that Encode: 
     (A) Plant disease resistance genes. Plant defenses are often activated by specific interaction between the product of a disease resistance gene (R) in the plant and the product of a corresponding avirulence (Avr) gene in the pathogen. A plant variety can be transformed with cloned resistance gene to engineer plants that are resistant to specific pathogen strains. See, for example Jones et al., Science 266: 789 (1994) (cloning of the tomato Cf-9 gene for resistance to  Cladosporium fuivum ); Martin et al., Science 262: 1432 (1993) (tomato Pto gene for resistance to  Pseudomonas synngae  pv. tomato encodes a protein kinase); Mindrinos et al, Cell 78: 1089 (1994) ( Arabidopsis  RSP2 gene for resistance to  Pseudomonas syringae ). 
     (B) A  Bacillus thunngiensis  protein, a derivative thereof or a synthetic polypeptide modeled thereon. See, for example, Geiser et al.,  Gene  48: 109 (1986), who disclose the cloning and nucleotide sequence of a Bt δ-endotoxin gene. Moreover, DNA molecules encoding δ-endotoxin genes can be purchased from American Type Culture Collection (Rockville, Md.), for example, under ATCC Accession Nos. 40098, 67136, 31995 and 31998. Other examples of  Bacillus thuringiensis  transgenes being genetically engineered are given in the following patents and hereby are incorporated by reference: U.S. Pat. Nos. 5,188,960; 5,689,052; 5,880,275; and WO 97/40162. 
     (C) A lectin. See, for example, the disclosure by Van Damme et al.,  Plant Molec. Biol . 24: 25 (1994), who disclose the nucleotide sequences of several  Clivia miniata  mannose-binding lectin genes. 
     (D) A vitamin-binding protein such as avidin. See PCT application US93/06487 the contents of which are hereby incorporated by reference. The application teaches the use of avidin and avidin homologues as larvicides against insect pests. 
     (E) An enzyme inhibitor, for example, a protease inhibitor or an amylase inhibitor. See, for example, Abe et al.,  J. Biol. Chem . 262: 16793 (1987) (nucleotide sequence of rice cysteine proteinase inhibitor), Huub et al.,  Plant Molec. Biol . 21: 985 (1993) (nucleotide sequence of cDNA encoding tobacco proteinase inhibitor I), and Sumitani et al.,  Biosci. Biotech. Biochem . 57: 1243 (1993) (nucleotide sequence of  Streptomyces nitrosporeus  α-amylase inhibitor) and U.S. Pat. No. 5,494,813. 
     (F) An insect-specific hormone or pheromone such as an ecdysteroid and juvenile hormone, a variant thereof, a mimetic based thereon, or an antagonist or agonist thereof. See, for example, the disclosure by Hammock et al., Nature 344: 458 (1990), of baculovirus expression of cloned juvenile hormone esterase, an inactivator of juvenile hormone. 
     (G) An insect-specific peptide or neuropeptide which, upon expression, disrupts the physiology of the affected pest. For example, see the disclosures of Regan,  J. Biol. Chem . 269: 9 (1994) (expression cloning yields DNA coding for insect diuretic hormone receptor), and Pratt et al.,  Biochem. Biophys. Res. Comm . 163: 1243 (1989) (an allostatin is identified in  Diploptera puntata ). See also U.S. Pat. No. 5,266,317 to Tomalski et al., who disclose genes encoding insect-specific, paralytic neurotoxins. 
     (H) An insect-specific venom produced in nature by a snake, a wasp, etc. For example, see Pang et al.,  Gene  116: 165 (1992), for disclosure of heterologous expression in plants of a gene coding for a scorpion insectotoxic peptide. 
     (I) An enzyme responsible for an hyperaccumulation of a monterpene, a sesquiterpene, a steroid, hydroxamic acid, a phenylpropanoid derivative or another non-protein molecule with insecticidal activity. 
     (J) An enzyme involved in the modification, including the post-translational modification, of a biologically active molecule; for example, a glycolytic enzyme, a proteolytic enzyme, a lipolytic enzyme, a nuclease, a cyclase, a transaminase, an esterase, a hydrolase, a phosphatase, a kinase, a phosphorylase, a polymerase, an elastase, a chitinase and a glucanase, whether natural or synthetic. See PCT application WO 93/02197 in the name of Scott et al., which discloses the nucleotide sequence of a callase gene. DNA molecules which contain chitinase-encoding sequences can be obtained, for example, from the ATCC under Accession Nos. 39637 and 67152. See also Kramer et al.,  Insect Biochem. Molec. Biol .23: 691 (1993), who teach the nucleotide sequence of a cDNA encoding tobacco hookworm chitinase, and Kawalleck et al.,  Plant Molec. Biol . 21: 673 (1993), who provide the nucleotide sequence of the parsley ubi4-2 polyubiquitin gene. 
     (K) A molecule that stimulates signal transduction. For example, see the disclosure by Botella et al,  Plant Molec. Biol . 24: 757 (1994), of nucleotide sequences for mung bean calmodulin cDNA clones, and Griess et al.,  Plant Physiol .104: 1467 (1994), who provide the nucleotide sequence of a maize calmodulin cDNA clone. 
     (L) A hydrophobic moment peptide. See PCT application WO95/16776 (disclosure of peptide derivatives of Tachyplesin which inhibit fungal plant pathogens) and PCT application WO95/18855 (teaches synthetic antimicrobial peptides that confer disease resistance), the respective contents of which are hereby incorporated by reference. 
     (M) A membrane permease, a channel former or a channel blocker. For example, see the disclosure by Jaynes et al.,  Plant Sci . 89: 43 (1993), of heterologous expression of a cecropin-β lytic peptide analog to render transgenic tobacco plants resistant to  Pseudomonas solanacearum.    
     (N) A viral-invasive protein or a complex toxin derived therefrom. For example, the accumulation of viral coat proteins in transformed plant cells imparts resistance to viral infection and/or disease development effected by the virus from which the coat protein gene is derived, as well as by related viruses. See Beachy et al.,  Ann. Rev. Phytopathol .28: 451 (1990). Coat protein-mediated resistance has been conferred upon transformed plants against alfalfa mosaic virus, cucumber mosaic virus, tobacco streak virus, potato virus X, potato virus Y, tobacco etch virus, tobacco rattle virus and tobacco mosaic virus. Id. 
     (O) An insect-specific antibody or an immunotoxin derived therefrom. Thus, an antibody targeted to a critical metabolic function in the insect gut would inactivate an affected enzyme, killing the insect. Cf. Taylor et al., Abstract #497, SEVENTH INT&#39;L SYMPOSIUM ON MOLECULAR PLANT-MICROBE INTERACTIONS (Edinburgh, Scotland, 1994) (enzymatic inactivation in transgenic tobacco via production of single-chain antibody fragments). 
     (P) A virus-specific antibody. See, for example, Tavladoraki et al.,  Nature  366: 469 (1993), who show that transgenic plants expressing recombinant antibody genes are protected from virus attack. 
     (Q) A developmental-arrestive protein produced in nature by a pathogen or a parasite. Thus, fungal endo: α-1,4-D-polygalacturonases facilitate fungal colonization and plant nutrient release by solubilizing plant cell wall homo-α-1,4-D-galacturonase. See Lamb et al.,  Bio/Technology  10: 1436 (1992). The cloning and characterization of a gene which encodes a bean endopolygalacturonase-inhibiting protein is described by Toubart et al.,  Plant J . 2: 367 (1992). 
     (R) A developmental-arrestive protein produced in nature by a plant. For example, Logemann et al.,  Bio/Technology  10: 305 (1992), have shown that transgenic plants expressing the barley ribosome-inactivating gene have an increased resistance to fungal disease. 
     (S) Genes involved in the Systemic Acquired Resistance (SAR) Response and/or the pathogenesis related genes. Briggs, S., Current Biology, 5(2) (1995). 
     (T) Antifungal genes (Cornelissen and Melchers, PI. Physiol. 101:709-712, (1993) and Parijs et al., Planta 183:258-264, (1991) and Bushnell et al., Can. J. of Plant Path. 20(2):137-149 (1998). 
     2. Transgenes that Confer Resistance to A Herbicide, for Example: 
     (A) A herbicide that inhibits the growing point or meristem, such as an imidazalinone or a sulfonylurea. Exemplary genes in this category code for mutant ALS and AHAS enzyme as described, for example, by Lee et al., EMBO J . 7: 1241 (1988), and Miki et al.,  Theor. Appl.Genet . 80: 449 (1990), respectively. See also, U.S. Pat. Nos. 5,605,011; 5,013,659; 5,141,870; 5,767,361; 5,731,180; 5,304,732; 4,761,373; 5,331,107; 5,928,937; and 5,378,824; and international publication WO 96/33270, which are incorporated herein by reference in their entireties for all purposes. 
     (B) Glyphosate (resistance imparted by mutant 5-enolpyruvl-3-phosphikimate synthase (EPSP), and aroA genes, respectively) and other phosphono compounds such as glufosinate (phosphinothricin acetyl transferase (PAT) and  Streptomyces hygroscopicus  phosphinothricin acetyl transferase (bar) genes), and pyridinoxy or phenoxy proprionic acids and cycloshexones (ACCase inhibitor-encoding genes). See, for example, U.S. Pat. No. 4,940,835 to Shah et al., which discloses the nucleotide sequence of a form of EPSPS which can confer glyphosate resistance. U.S. Pat. No. 5,627,061 to Barry et al. also describes genes encoding EPSPS enzyrmes. See also U.S. Pat. Nos. 6,248,876 B1; 6,040,497; 5,804,425; 5,633,435; 5,145,783; 4,971,908; 5,312,910; 5,188,642; 4,940,835; 5,866,775; 6,225,114 B1; 6,130,366; 5,310,667; 4,535,060; 4,769,061; 5,633,448; 5,510,471; Re. 36,449; RE 37,287 E; and U.S. Pat No. 5,491,288; and international publications WO 97/04103; WO 97/04114; WO 00/66746; WO 01/66704; WO 00/66747 and WO 00/66748, which are incorporated herein by reference in their entirety. Glyphosate resistance is also imparted to plants that express a gene that encodes a glyphosate oxido-reductase enzyme as described more fully in U.S. Pat. Nos. 5,776,760 and 5,463,175, which are incorporated herein by reference in their entirety. In addition glyphosate resistance can be imparted to plants by the over expression of genes encoding glyphosate N-acetyltransferase. See, for example, U.S. application Ser. Nos. 60/244,385; 60/377,175 and 60/377,719. 
     A DNA molecule encoding a mutant aroA gene can be obtained under ATCC accession No. 39256, and the nucleotide sequence of the mutant gene is disclosed in U.S. Pat. No. 4,769,061 to Comai. European patent application No. 0 333 033 to Kumada et al. and U.S. Pat. No. 4,975,374 to Goodman et al. disclose nucleotide sequences of glutamine synthetase genes which confer resistance to herbicides such as L-phosphinothricin. The nucleotide sequence of a phosphinothricin-acetyl-transferase gene is provided in European patent No. 0 242 246 and 0 242 236 to Leemans et al. De Greef et al.,  Bio/Technology  7: 61 (1989), describe the production of transgenic plants that express chimeric bar genes coding for phosphinothricin acetyl transferase activity. See also, U.S. Pat. Nos. 5,969,213; 5,489,520; 5,550,318; 5,874,265; 5,919,675; 5,561,236; 5,648,477; 5,646,024; 6,177,616 B1; and 5,879,903, which are incorporated herein by reference in their entirety. Exemplary of genes conferring resistance to phenoxy proprionic acids and cycloshexones, such as sethoxydim and haloxyfop, are the Accl-Sl, Accl-S2 and Accl-S3 genes described by Marshall et al.,  Theor. Appl. Genet . 83: 435 (1992). 
     (C) A herbicide that inhibits photosynthesis, such as a triazine (psbA and gs+genes) and a benzonitrile (nitrilase gene). Przibilla et al.,  Plant Cell  3: 169 (1991), describe the transformation of  Chlamydomonas  with plasmids encoding mutant psbA genes. Nucleotide sequences for nitrilase genes are disclosed in U.S. Pat. No. 4,810,648 to Stalker, and DNA molecules containing these genes are available under ATCC Accession Nos. 53435, 67441 and 67442. Cloning and expression of DNA coding for a glutathione S-transferase is described by Hayes et al.,  Biochem. J . 285: 173 (1992). 
     (D) Acetohydroxy acid synthase, which has been found to make plants that express this enzyme resistant to multiple types of herbicides, has been introduced into a variety of plants (see, e.g., Hattori et al. (1995) Mol Gen Genet 246:419). Other genes that confer tolerance to herbicides include: a gene encoding a chimeric protein of rat cytochrome P4507A1 and yeast NADPH-cytochrome P450 oxidoreductase (Shiota et al. (1994) Plant PhysiolPlant Physiol 106:17), genes for glutathione reductase and superoxide dismutase (Aono et al. (1995) Plant Cell Physiol 36:1687, and genes for various phosphotransferases (Datta et al. (1992) Plant Mol Biol 20:619). 
     (E) Protoporphyrinogen oxidase (protox) is necessary for the production of chlorophyll, which is necessary for all plant survival. The protox enzyme serves as the target for a variety of herbicidal compounds. These herbicides also inhibit growth of all the different species of plants present, causing their total destruction. The development of plants containing altered protox activity which are resistant to these herbicides are described in U.S. Pat. Nos. 6,288,306 B1; 6,282,837 B1; and 5,767,373; and international publication WO 01/12825, which are incorporated herein by reference in their entireties of all purposes. 
     3. Transgenes that Confer or Contribute to a Value-added Trait, such as: 
     (A) Modified fatty acid metabolism, for example, by transforming a plant with an antisense gene of stearoyl-ACP desaturase to increase stearic acid content of the plant. See Knultzon et al,  Proc. Natt. Acad. Sci. USA  89: 2624 (1992). 
     (B) Decreased Phytate Content 
     (1) Introduction of a phytase-encoding gene would enhance breakdown of phytate, adding more free phosphate to the transformed plant. For example, see Van Hartingsveldt et al.,  Gene  127: 87 (1993), for a disclosure of the nucleotide sequence of an  Aspergillus niger  phytase gene. 
     (2) A gene could be introduced that reduces phytate content. In maize, this, for example, could be accomplished, by cloning and then reintroducing DNA associated with the single allele which is responsible for maize mutants characterized by low levels of phytic acid. See Raboy et al.,  Maydica  35: 383 (1990). (

     Genetic Marker Profile Through SSR 
     The present invention comprises a hybrid corn plant which is characterized by the molecular and physiological data presented herein and in the representative sample of said hybrid and of the inbred parents of said hybrid deposited with the ATCC. 
     As discussed, supra, in addition to phenotypic observations, a plant can also be described by its genotype. The genotype of a plant can be described through a genetic marker profile which can identify plants of the same variety, a related variety or be used to determine or validate a pedigree. Genetic marker profiles can be obtained by techniques such as Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats (SSRs) which are also referred to as Microsatellites, and Single Nucleotide Polymorphisms (SNPs). For example, see Berry, Don, et al., “Assessing Probability of Ancestry Using Simple Sequence Repeat Profiles: Applications to Maize Hybrids and Inbreds”, Genetics, 2002, 161:813-824, which is incorporated by reference herein in its entirety. 
     Particular markers used for these purposes are not limited to the set of markers disclosed herewithin, but are envisioned to indude any type of marker and marker profile which provides a means of distinguishing varieties. In addition to being used for identification of inbred parents, hybrid variety 35D45, a hybrid produced through the use of 35D45 or its parents, and the identification or verification of pedigree for progeny plants produced through the use of 35D45, the genetic marker profile is also useful in breeding and developing single gene conversions. 
     Means of performing genetic marker profiles using SSR polymorphisms are well known in the art. SSRs are genetic markers based on polymorphisms in repeated nucleofide sequences, such as microsatellites. A marker system based on SSRs can be highly informative in linkage analysis relative to other marker systems in that multiple alleles may be present. Another advantage of this type of marker is that, through use of flanking primers, detection of SSRs can be achieved, for example, by the polymerase chain reaction (PCR), thereby eliminating the need for labor-intensive Southern hybridization. The PCR™ detection is done by use of two oligonucleotide primers flanking the polymorphic segment of repetitive DNA. Repeated cydes of heat denaturation of the DNA followed by annealing of the primers to their complementary sequences at low temperatures, and extension of the annealed primers with DNA polymerase, comprise the major part of the methodology. 
     Following amplification, markers can be scored by gel electrophoresis of the amplification products. Scoring of marker genotype is based on the size of the amplified fragment as measured by molecular weight (MW) rounded to the nearest integer. While variation in the primer used or in laboratory procedures can affect the reported molecular weight, relative values should remain constant regardless of the specific primer or laboratory used. When comparing lines it is preferable if all SSR profiles are performed in the same lab. An SSR service is available to the public on a contractual basis by Paragen, research Trianbgle Park, N. C. , (formerly Celera AgGen of Davis, Calif. 
     Primers used for the SSRs suggested herein are publicly available and may be found in the Maize GDB using the World Wide Web prefix followed by maizegdb.org (maintained by the USDA Agricultural Research Service), in Sharopova et al. (Plant Mol. Biol. 48(5-6):463-481). Lee et al. (Plant Mol. Biol. 48(5-6); 453-461). Some marker information may be available from Paragen. 
     Map information is provided in centimorgans (cM) and based on a composite map developed by Pioneer Hi-Bred. This composite map was created: by identifying common markers between various maps and using linear regression to place the intermediate markers. The reference map used was UMC98. Map positions for the SSR markers reported herein will vary depending on the mapping population used. Any chromosome numbers reported in parenthesis represent other chromosome locations for such marker that have been reported in the literature or on the Maize GDB. Map positions are available on the Maize GDB for a variety of different mapping populations.

     A genetic marker profile of a hybrid should be the sum of its inbred parents, e.g., if one inbred parent had the allele 168 (base pairs) at a particular locus, and the other inbred parent had 172 the hybrid is 168.172 (heterozygous) by inference. Subsequent generations of progeny produced by selection and breeding are expected to be of genotype 168 (homozygous), 172 (homozygous), or 168.172 for that locus position. When the F1 plant is used to produce an inbred, the locus should be either 168 or 172 for that position. 
     In addition, plants and plant parts substantially benefiting from the use of 35D45 in their development such as 35D45 comprising a single gene conversion, transgene, or genetic sterility factor, may be identified by having a molecular marker profile with a high percent identity to 35D45. Such a percent identity might be 98%, 99%, 99.5% or 99.9% identical to 3SD5. 
     The SSR profile of 35D45 also can be used to identify essentially derived varieties and other progeny lines developed from the use of 35D45, as well as cells and other plant parts thereof. Progeny plants and plant parts produced using 35D45 may be identified by having a molecular marker profile of at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 99.5% genetic contribution from hybrid maize plant 35D45. 
     INDUSTRIAL APPLICABILITY 
     Maize is used as human food, livestock feed, and as raw material in industry. The food uses of maize, in addition to human consumption of maize kernels, include both products of dry- and wet-milling industries. The principal products of maize dry milling are grits, meal and flour. The maize wet-milling industry can provide maize starch, maize syrups, and dextrose for food use. Maize oil is recovered from maize germ, which is a by-product of both dry- and wet-milling industries. 
     Maize, including both grain and non-grain portions of the plant, is also used extensively as livestock feed, primarily for beef cattle, dairy cattle, hogs, and poultry. 
     Industrial uses of maize include production of ethanol, maize starch in the wet-milling industry and maize flour in the dry-milling industry. The industrial applications of maize starch and flour are based on functional properties, such as viscosity, film formation, adhesive properties, and ability to suspend particles. The maize starch and flour have application in the paper and textile industries. Other industrial uses include applications in adhesives, building materials, foundry binders, laundry starches, explosives, oil-well muds, and other mining applications. 
     Plant parts other than the grain of maize are also used in industry: for example, stalks and husks are made into paper and wallboard and cobs are used for fuel and to make charcoal. 
     The seed of the hybrid maize plant, the plant produced from the seed, a plant produced from crossing of maize hybrid plant 35D45 and various parts of the hybrid maize plant and transgenic versions of the foregoing, can be utilized for human food, livestock feed, and as a raw material in industry. 
     DEPOSITS
