## Background
FIELD OF INVENTION
This invention is in the field of wheat (Triticum aestivum L.) breeding, specifically relating to a wheat variety designated W040511B1.
BACKGROUND OF INVENTION
There are numerous steps involving significant technical human intervention in the development of any novel, desirable plant germplasm. Plant breeding begins with the analysis and definition of problems and weaknesses of the current germplasm, the establishment of program goals, and the definition of specific breeding objectives. The next step is selection of germplasm that possess the traits to meet the program goals. The goal is to combine in a single variety an improved combination of desirable traits from the parental germplasm. These traits may include, but are not limited to higher seed yield, resistance to diseases and/or insects, tolerance to drought and/or heat, altered milling properties, abiotic stress tolerance, improvements in compositional traits, and better agronomic characteristics.
Processes which lead to the final step of marketing and distribution can take from approximately six to twelve years of significant technical human intervention starting from the time the first cross is made. Therefore, development of new varieties is a time-consuming process that requires precise forward planning, efficient use of resources, and a minimum in changes of direction. Stable, high yielding wheat varieties that are agronomically sound and which maximize the amount of grain produced on the land used are selected and developed to provide superior wheat plant varieties. Significant human intervention is required.
Wheat is grown worldwide and is the most widely adapted cereal. There are five main wheat market classes. They include the four common wheat (Triticum aestivum L.) classes: hard red winter, hard red spring, soft red winter, and white. The fifth class is durum (Triticum turgidum L.). Common wheats are used in a variety of food products such as bread, cookies, cakes, crackers, and noodles. In general the hard wheat classes are milled into flour used for breads and the soft wheat classes are milled into flour used for pastries and crackers. Wheat starch is also used in the paper industries, as laundry starches, and in other products.

DETAILED DESCRIPTION
The present invention relates to a new and distinctive wheat (Triticum aestivum L.), variety designated W040511B1, which has been the result of years of careful breeding and selection in a comprehensive wheat breeding program.
The modified pedigree selection method of breeding was used to derive this line from elite germplasm. The first cross was made in 2003 and breeding and selection continued until 2013. W040511B1 represents a significant advancement in elite germplasm adapted to the United States.
Field crops are bred through techniques that take advantage of the plant's method of pollination, such as self-pollination, sib-pollination or cross-pollination. As used herein, the term cross-pollination includes pollination with pollen from a flower on a different plant from a different family or line and does not include self-pollination or sib-pollination. Wheat plants (Triticum aestivum L.), are recognized to be naturally self-pollinated plants which, while capable of undergoing cross-pollination, rarely do so in nature. Thus intervention for control of pollination is needed for the establishment of superior varieties.
Provided are methods of producing progeny with a new combination of genetic traits by cross pollinating one wheat plant with another by emasculating flowers of a designated female plant and pollinating the female parent with pollen from the designated male parent. Suitable methods of cross-pollination of wheat plants are described, for example, in U.S. Pat. No. 8,809,654, which is herein incorporated by reference, but other methods can be used, or modified, as is known to those skilled in the art.
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 heterozygous plants each that differ at a number of gene loci will produce a population of plants that differ genetically and will not be uniform. Regardless of parentage, 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. The term “homozygous plant” is hereby defined as a plant with homozygous genes at 95% or more of its loci.
Choice of breeding or selection methods depends on the mode of plant reproduction, the heritability of the trait(s) being improved, and the type of variety used commercially (e.g., F1 hybrid variety, pureline variety, etc.). For highly heritable traits, a choice of superior individual plants evaluated at a single location will be effective, whereas for traits with low heritability, selection can be based on mean values obtained from replicated evaluations of families of related plants. Popular selection methods commonly include pedigree selection, modified pedigree selection, mass selection, and recurrent selection.
The complexity of inheritance influences choice of the breeding method. For example, pedigree breeding, backcross breeding, single seed descent, and bulk breeding, which are each described in U.S. Pat. No. 8,809,654 (incorporated herein by reference), can be used. Each wheat breeding program may include a periodic, objective evaluation of the efficiency of the breeding procedure. Evaluation criteria vary depending on the goal and objectives, but may include gain from selection per year based on comparisons to an appropriate standard, overall value of the advanced breeding lines, and number of successful varieties produced per unit of input (e.g., per year, per dollar expended, etc.).
Various recurrent selection techniques can be used to improve quantitatively inherited traits controlled by numerous genes. The use of recurrent selection in self-pollinating crops depends on the ease of pollination and the number of hybrid offspring from each successful cross. Recurrent selection can be used to improve populations of either self- or cross-pollinated crops. A genetically variable population of heterozygous individuals is either identified or created by intercrossing several different parents. The best plants are selected based on individual superiority, outstanding progeny, or excellent combining ability. The selected plants are intercrossed to produce a new population in which further cycles of selection are continued. Plants from the populations can be selected and selfed to create new varieties.
Wheat variety W040511B1 can be used as the female or the male parent in biparental crosses in order to develop new and valuable wheat varieties. Wheat normally self-pollinates in nature. Wheat cross-pollination can be achieved by emasculating a designated female plant and pollinating the female plant with pollen from the designated male parent.
In order to cross pollinate one wheat plant with another to produce progeny with a new combination of genetic traits, a method of cross-pollination is employed. Cross-pollination is known to those skilled in the art. Wheat cross-pollination is achieved by emasculating flowers of a designated female plant and pollinating the female parent with pollen from the designated male parent. The following method was employed to cross-pollinate the wheat plants, but other methods can be used, or modified, as is known to those skilled in the art.
The designated female wheat plant is emasculated before its anthers shed pollen to avoid self-pollination. Emasculation is done by selecting an immature spike on the designated female parent plant that has not started to bloom and shed any viable pollen. Each spike consists of a series of spikelets composed of florets which each contain one ovary with a feathery stigma and three anthers. Typically all but the two primary florets are removed from each spikelet by using tweezers. The glumes of each remaining floret can be trimmed back about 50% using scissors to expose the immature anthers. The tweezers are used to spread the glumes slightly open while at the same time surrounding the anthers. The anthers can then be removed by gently grabbing and pulling them out of the flower with the tweezers in an upward motion. With skill, all three anthers can be removed at once, but this must be confirmed visually before moving to the next flower. Repeated attempts to remove any remaining anthers increases the risk of damage to the stigma and ovary and greatly reduce the frequency of cross-pollination. After all the florets are emasculated on a spike, it is covered with a cellophane bag to prevent pollination with stray pollen from surrounding plants. One to three days after the female spike is emasculated a mature spike that is shedding pollen is selected from the designated male plant for cross-pollination using the approach method. The stem of the male spike is cut off at least one foot below the spike and typically the glumes of all the spikelets are trimmed back with scissors to encourage anther extrusion during pollination. The stem of the male spike is placed in a test tube full of water, which is attached to a stick implanted beside the emasculated female spike. The male spike is placed above the emasculated female spike(s) in the same cellophane bag and it is permitted to shed pollen naturally over the next several days. By waiting a few days after emasculation, one can ensure that no anthers or viable pollen has remained in the female spike and the stigmas become more receptive to cross-pollination. Emasculated female spikes that are effectively cross-pollinated by the designated male parent will typically set 10-30 seeds per spike. Depending on the breeding objectives, one to five spikes are typically cross-pollinated for each cross. Spikes from the cross are hand harvested and the F1 seed from the spikes are advanced to the F1 generation. The F1 plants can be used for used for subsequent cross-pollination or they can be advanced to the F2 generation for selection and further advancement. For the F2 grow out, 2500 to 3500 seeds are typically planted.
Plant breeding methods may include use of molecular markers, including techniques such as Starch Gel Electrophoresis, Isozyme Electrophoresis, 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), Single Nucleotide Polymorphisms (SNPs) and Quantitative Trait Loci (QTL) mapping.
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 homozygous lines in the breeding program and in the production of, for example, hybrid wheat. In an embodiment, the variety is used in the production of hybrid wheat. Double haploids are produced by the doubling of a set of chromosomes (1 N) from a heterozygous plant to produce a completely homozygous individual. This can be advantageous because the process omits the generations of selfing needed to obtain a homozygous plant from a heterozygous source. Hybrid wheat can be produced, for example, with the help of cytoplasmic male sterility, nuclear genetic male sterility, chemicals or a combination thereof.
A breeder uses various methods to help determine which plants should be selected from the segregating populations and ultimately which lines will be used 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 can be used to help determine which plants, which family of plants, and finally which lines are significantly better or different for one or more traits of interest. Experimental design methods can be used to control error so that differences between two 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. Five and one percent significance levels are customarily used to determine whether a difference that occurs for a given trait is real or due to the environment or experimental error.
Plant breeding is the genetic manipulation of plants. The goal of wheat breeding is to develop new, unique and superior wheat varieties. In practical application of a wheat breeding program, the breeder initially selects and crosses two or more parental lines, followed by repeated selfing and selection, producing many new genetic combinations. The breeder can theoretically generate billions of different genetic combinations via crossing, selfing and mutations. Each year, the plant breeder selects the germplasm to advance to the next generation. This germplasm is grown under unique and different geographical, climatic and soil conditions and further selections are then made during and at the end of the growing season.
Plants are tested to detect major faults and establish the level of superiority or improvement over current varieties. Research and development, breeding and testing processes, which lead to the final step of marketing and distribution, can take from six to twelve years from the time the first cross is made. Therefore, development of new varieties is a time-consuming process that requires precise forward planning, efficient use of resources, and a minimum of changes in direction.
According to the invention, there is provided a novel wheat variety, designated W040511B1 and processes for making W040511B1. This invention relates to seed of wheat variety W040511B1, to the plants of wheat variety W040511B1, to plant parts of wheat variety W040511B1, and to processes for making a wheat plant that comprise crossing wheat variety W040511B1 with another wheat plant. This invention also relates to processes for making a wheat plant containing in its genetic material one or more traits introgressed into W040511B1 through backcross conversion and/or transformation, and to the wheat seed, plant and plant parts produced thereby. This invention also relates to the creation of variants by mutagenesis or transformation of wheat W040511B1. This invention further relates to a hybrid wheat seed, plant or plant part produced by crossing the variety W040511B1 or a locus conversion of W040511B1 with another wheat variety.
Wheat varieties that are highly homogeneous, homozygous and reproducible are useful as commercial varieties. There are many analytical methods available to determine the homozygotic stability, phenotypic stability, and identity of these varieties.
In some embodiments, data can be collected from the observation of phenotypic traits over the life of the wheat plants in field experiments. Phenotypic characteristics observed can include traits such as seed yield, head configuration, glume configuration, seed configuration, lodging resistance, disease resistance, maturity. The genotype of a plant can also be examined. There are many laboratory-based techniques available for the analysis, comparison and characterization of plant genotype including, without limitation, Gel Electrophoresis, Isozyme Electrophoresis, 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). Gel electrophoresis is particularly useful in wheat. Wheat variety identification can occur, for example, through electrophoresis of gliadin, glutenin, albumin and globulin, and total protein extracts.
Wheat variety W040511B1 has shown uniformity and stability for all traits, as described in the following variety description information. It has been self-pollinated a sufficient number of generations, with careful attention to uniformity of plant type to ensure homozygosity and phenotypic stability. The line has been increased with continued observation for uniformity. No variant traits have been observed or are expected in W040511B1, as described in Table 1B.
Wheat variety W040511B1 is a common, soft red winter wheat. Variety W040511B1 demonstrates excellent yield potential with high test weight, very good resistance to Fusarium head blight (scab) and Soil-borne mosaic virus, and excellent resistance to stripe rust. Variety W040511B1 has medium maturity relative to other varieties in the primary region of adaptation. It has shown adaptation to the northern soft wheat regions based on tests conducted in Arkansas, Georgia, Illinois, Indiana, Kentucky, Michigan, Missouri, Mississippi, North Carolina, Ohio, Virginia, and Ontario, Canada.
Wheat variety W040511B1 was developed by from a cross between three homozygous lines W950304K1, 25W41, and 25R47. Wheat variety W040511B1, being substantially homozygous, can be reproduced by planting seeds of the line, growing the resulting wheat plants under self-pollinating or sib-pollinating conditions, and harvesting the resulting seed, using techniques familiar to the agricultural arts.
Wheat variety W040511B1 is a soft red winter wheat (Triticum aestivum L.) derived from a three parent cross made in 2003 as follows:

During the process of development, the plant populations as well as individual plants are evaluated for general health, agronomics, and stability at many stages. These evaluations typically include, but are not limited to, one or more of the following characteristics: plant architecture traits such as seedling coleoptile length, coleoptile color (presence of anthocyanin), juvenile plant growth habit, tillering, plant height, straw strength or lodging, flag leaf carriage at boot stage, leaf width and length, glaucosity of stems, leaves and spikes, pubescence of leaves and spikes, spike shape, spike density, spike awnedness, and plant color through-out stages of growth; plant growth characteristics, such as vernalization requirement, date for first stem joint emergence, heading date, flowering date, physiological maturity date and harvest maturity; tolerance to weather conditions, such as cold tolerance, resistance to heaving, tolerance to wet soils and standing water, drought and heat tolerance; and grain characteristics, such as grain yield, test weight, 1000 kernel weight, grain moisture, grain color, grain shape, grain protein, flour milling yield and baking characteristics.
During its development, wheat variety W040511B1 was assayed and/or planted in field trials and evaluated for a variety of traits and/or characteristics as compared to check varieties. The property(s) of appropriate check varieties include but are not limited to varieties with a similar relative maturity, varieties known to be susceptible to one or more particular diseases, insect, pathogen, field condition, weather condition, soil type or condition, and/or crop management practice, varieties known to be tolerant or resistant to one or more particular diseases, insect, pathogen, field condition, weather condition, soil type or condition, and/or crop management practice, varieties comprising one or more particular marker locus, and/or varieties derived from another appropriate variety or having a particular pedigree. Appropriate choice of check varieties for comparison assures an appropriate baseline and valid qualitative or quantitative assessment of any test varieties.
Throughout the course of the development of W040511B1, the plants can be tested for various traits including, but not limited to grain yield, test weight, heading date, harvest maturity, plant height, straw strength, pre-harvest sprout tolerance, resistance levels to leaf rust, stripe rust, tan spot, Septoria tritici blotch, Stagnospora nodorum blotch, powdery mildew, Fusarium (scab), wheat yellow mosaic virus and soilborne mosaic virus, and grain characteristics such as flour yield, flour protein, and baking characteristics.
The cultivar W040511B1 was bred and selected using a modified pedigree selection method for any and all of the following characteristics in the field environment: disease resistance, plant type, plant height, head type, straw strength, maturity, grain yield, test weight, and milling and baking characteristics. W040511B1 has been shown to be uniform and stable since the 7th generation, or for the last 4 generations. W040511B1 has shown no variants other than what would normally be expected due to environment.
Wheat variety W040511B1, being substantially homozygous, can be reproduced by planting seeds of the line, growing the resulting wheat plants under self-pollinating or sib-pollinating conditions, and harvesting the resulting seed, using techniques familiar to the agricultural arts.
When referring to area of adaptability, such term is used to describe the location with the environmental conditions that would be well suited for this wheat variety. Area of adaptability is based on a number of factors, for example: days to heading, winter hardiness, insect resistance, disease resistance, and drought resistance. Area of adaptability does not indicate that the wheat variety will grow in every location within the area of adaptability or that it will not grow outside the area.

In one aspect, wheat plants, plant parts and seeds are provided which have all or essentially all of the characteristics set forth in Table 1B. In one aspect wheat plants, plant parts and seeds are provided which have all or essentially all of the physiological and morphological characteristics of wheat variety W040511B1, representative seed having been deposited with the ATCC as disclosed herein.
Wheat variety W040511B1 can be further reproduced by tissue culture and regeneration. Tissue culture of various tissues of wheat and regeneration of plants therefrom is well known and widely published. Thus, in another aspect provided are cells which upon growth and differentiation produce wheat plants capable of having the physiological and morphological characteristics of wheat variety W040511B1.
As used herein, the term “plant parts” includes, without limitation, plant protoplasts, plant cell tissue cultures from which wheat plants can be regenerated, plant calli, plant clumps, plant cells, embryos, pollen, ovules, pericarp, seed, flowers, florets, heads, spikes, leaves, roots, root tips, anthers, and the like. When indicating that a plant is crossed or selfed this indicates that any plant part of the plant can be used. For instance the plant part does not need to be attached to the plant during the crossing or selfing, only the pollen might be used.
In one aspect, a wheat plant containing a locus conversion or an essentially derived variety of W040511B1 is provided. As determined by the UPOV Convention, essentially derived varieties may be obtained for example by the selection of a natural or induced mutant, or of a somaclonal variant, the selection of a variant individual from plants of the initial variety, backcrossing, or transformation by genetic engineering. An essentially derived variety of W040511B1 is further defined as one whose production requires the repeated use of variety W040511B1 or is predominately derived from variety W040511B1. International Convention for the Protection of New Varieties of Plants, as amended on Mar. 19, 1991, Chapter V, Article 14, Section 5(c).
A locus conversion refers to plants within a variety that have been modified in a manner that retains the overall genetics of the variety and further comprises one or more loci with a specific desired trait, such as male sterility, insect, disease or herbicide resistance. Examples of single locus conversions include mutant genes, transgenes and native traits finely mapped to a single locus. One or more locus conversion traits may be introduced into a single wheat variety. As used herein, the phrase ‘comprising a’ transgene, transgenic event or locus conversion means one or more transgenes, transgenic events or locus conversions.
Any DNA sequences, 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”. Methods for producing transgenic plants and in particular embodiments, transformed versions of the wheat variety W040511B1 and methods for producing such plants are provided.
Numerous methods for plant transformation have been developed, including biological protocols, such as using Agrobacterium, and physical techniques, such as biolistics and direct gene transfer. In addition, expression vectors and in vitro culture methods for plant cell or tissue transformation and regeneration of plants are available. 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 or coding sequence under the control of or operatively linked to a regulatory element, such as a promoter. The vector may contain one or more genes or coding sequences and one or more regulatory elements. The regulatory element or promoter can be heterologous to the gene or coding sequence.
Various elements can be introduced into the plant genome, including but are not limited to genes; coding sequences; inducible, constitutive, and tissue specific promoters; enhancing sequences; and signal and targeting sequences. As used herein, when used in transformation, a gene generally references the coding sequence or cDNA which does not include intron sequences not encoding a polypeptide.
A genetic trait, engineered into a particular wheat plant using transformation techniques, can be moved into another line using traditional breeding techniques that are well known in the plant breeding arts. For example, a backcrossing approach can be used to move a transgene from a transformed wheat plant to an elite wheat variety to provide resulting progeny comprising a transgene. As used herein, “crossing” can refer to a simple X by Y cross, or the process of backcrossing, depending on the context. The term “breeding cross” excludes the processes of selfing or sibbing.
Transgenic wheat plants according to the present invention can be harvested to produce a foreign protein in commercial quantities. The foreign protein can be extracted from a tissue of interest, such as a seed, or from total biomass by known methods. The approximate chromosomal location of the integrated DNA molecule can be determined from a genetic map generated, for example, via conventional RFLP, PCR, and SSR analysis. 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, SNPS and sequencing, all of which are conventional techniques.
As described herein, genes or coding sequences can be expressed in transformed plants. More particularly, plants can be genetically engineered to express various phenotypes of agronomic interest. A single gene or locus conversion or at least about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35 or 40 or more genes or locus conversions and less than about 100, 90, 80, 70, 60, 50, 40, 30, 20, 15, or 10 genes or locus conversions may be introduced into a plant or comprised in the genome of the wheat plant. Combinations or stacks of two or more genes or coding sequences described herein can be used. Through the transformation of wheat the expression of genes can be modulated to enhance disease resistance, insect resistance, herbicide resistance, water stress tolerance and agronomic traits as well as grain quality traits. These traits and the genes and organisms which may be targets are described in U.S. Pat. No. 8,809,554, which is incorporated herein by reference in its entirety for this purpose. Transformation can also be used to insert DNA sequences which control or help control male-sterility. DNA sequences native to wheat as well as non-native DNA sequences can be transformed into wheat and used to modulate levels of native or non-native proteins. The sequences can be heterologous comprising a coding sequence operably linked to a heterologous regulatory element, such as a promoter. Anti-sense technology, various promoters, targeting sequences, enhancing sequences, and other DNA sequences can be inserted into the wheat genome for the purpose of modulating the expression of proteins.
Exemplary genes which can be used include, but are not limited to, genes that confer resistance to pests such as Hessian fly, wheat stem sawfly, cereal leaf beetle, and/or green bug or disease, to pathogens Cladosporium fulvum Pseudomonas syringae Fusarium graminearum Schwabe, wheat rusts, Septoria tritici, Septoria nodorum, powdery mildew, Helminthosporium diseases, smuts, bunts, Fusarium diseases, bacterial diseases, and viral diseases.

Genes that confer agronomic enhancements, nutritional enhancements, or industrial enhancements can also be used. Such genes are described for example in U.S. Pat. No. 8,809,654, the disclosure of which is herein incorporated by reference in for this purpose. Such enhancements include, without limitation, improved tolerance to water stress from drought or high salt water condition. See e.g. U.S. Pat. Nos. 5,981,842, 5,780,709, international patent applications WO 92/19731, WO 92/19731 the disclosures of each of which is herein incorporated by reference for this purpose.
In some embodiments, methods of treating W040511B1 with a mutagen and the plant produced by mutagenesis of W040511B1 are provided. Backcross conversions of wheat variety W040511B1 are also described. A backcross conversion occurs when DNA sequences are introduced through traditional (non-transformation) breeding techniques, such as backcrossing. DNA sequences, whether naturally occurring or transgenes, may be introduced using these traditional breeding techniques. Desired traits transferred through this process include, but are not limited to, nutritional enhancements, industrial enhancements, disease resistance, insect resistance, herbicide resistance, agronomic enhancements, grain quality enhancement, waxy starch, breeding enhancements, seed production enhancements, and male sterility. Descriptions of some of the cytoplasmic male sterility genes, nuclear male sterility genes, chemical hybridizing agents, male fertility restoration genes, and methods of using the aforementioned are discussed in “Hybrid Wheat by K. A. Lucken (pp. 444-452 In Wheat and Wheat Improvement, ed. Heyne, 1987). Examples of genes for other traits which can be used with the methods, plants and plant parts described herein include: Leaf rust resistance genes (Lr series such as Lr1, Lr10, Lr21, Lr22, Lr22a, Lr32, Lr37, Lr41, Lr42, and Lr43), Fusarium head blight-resistance genes (QFhs.ndsu-3B and QFhs.ndsu-2A), Powdery Mildew resistance genes (Pm21), common bunt resistance genes (Bt-10), and wheat streak mosaic virus resistance gene (Wsm1), Russian wheat aphid resistance genes (Dn series such as Dn1, Dn2, Dn4, Dn5), Black stem rust resistance genes (Sr38), Yellow rust resistance genes (Yr series such as Yr1, YrSD, Yrsu, Yr17, Yr15, YrH52), Aluminum tolerance genes (Alt(BH)), dwarf genes (Rht), vernalization genes (Vrn), Hessian fly resistance genes (H9, H10, H21, H29), grain color genes (R/r), glyphosate resistance genes (EPSPS), glufosinate genes (bar, pat) and water stress tolerance genes (Hva1, mtlD). The trait of interest is transferred from the donor parent to the recurrent parent, in this case, the wheat 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 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.
Methods of developing a backcross conversion W040511B1 wheat plant are provided including the step of repeated backcrossing to wheat variety W040511B1. The number of backcrosses made may be 2, 3, 4, 5, 6, 7, 8 or greater, and fewer than 50, 40, 30, 25, 20, 15, 10, 9, or 8. The specific number of backcrosses used will depend upon the genetics of the donor parent and whether molecular markers are utilized in the backcrossing program. Provided are plants and plant populations that are produced from backcrossing methods, transformation, locus conversion, or otherwise produced, and combinations thereof and that retain at least 70%, 75%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8%, or 99.9% or 99.95%, 99.98%, 99.985%, 99.99% or 99.995% of the genetic profile of wheat variety W040511B1. The percentage of the genetics retained in the backcross conversion may be measured by either pedigree analysis or through the use of genetic techniques such as molecular markers or electrophoresis. Such methods and techniques are described in U.S. Pat. No. 8,809,654, the disclosure of which is herein incorporated by reference for this purpose. The backcross conversion or locus conversion developed from this method may be similar to W040511B1 for the results listed in Table 1B. Such similarity may be measured by a side by side phenotypic comparison, with differences and similarities determined at a 5% significance level, when appropriate in environmental conditions that account for the trait being transferred. For example, herbicide should not be applied in the phenotypic comparison of herbicide resistant backcross conversion of W040511B1 when compared back to W040511B1.
Described are methods for using wheat variety W040511B1 in plant breeding and plants and plant populations produced by such methods. For example, wheat variety W040511B1 can be crossed with another variety of wheat to form a first generation population of F1 plants. This first generation population of F1 plants will comprise an essentially complete set of the alleles of wheat variety W040511B1. Also provided are methods and plants which use transgenic or backcross conversions of wheat variety W040511B1 to produce first generation F1 plants.
A method of developing a W040511B1-progeny wheat plant comprising crossing W040511B1 with a second wheat plant and performing a breeding method is also described. An exemplary method for producing a line derived from wheat variety W040511B1 is as follows. Wheat variety W040511B1 is crossed with another variety of wheat, such as an elite variety. The F1 seed derived from this cross is grown to form a homogeneous population. The F1 seed contains one set of the alleles from variety W040511B1 and one set of the alleles from the other wheat variety. The F1 genome is 50% variety W040511B1 and 50% of the other elite variety. The F1 seed is grown and allowed to self, thereby forming F2 seed. On average the F2 seed would have derived 50% of its alleles from variety W040511B1 and 50% from the other wheat variety, but various individual plants from the population can have a much greater percentage of their alleles derived from W040511B1. The F2 seed is grown and selection of plants made based on visual observation and/or measurement of traits. The W040511B1-derived progeny that exhibit one or more of the desired W040511B1-derived traits are selected and each plant is harvested separately. This F3 seed from each plant is grown in individual rows and allowed to self. Then selected rows or plants from the rows are harvested and threshed individually. The selections based on visual observation and/or measurements for desirable traits of the plants, such as one or more of the desirable W040511B1-derived traits are made. The process of growing and selection is repeated any number of times until a homozygous W040511B1-derived wheat plant is obtained. The homozygous W040511B1-derived wheat plant contains desirable traits derived from wheat variety W040511B1, some of which may not have been expressed by the other original wheat variety to which wheat variety W040511B1 was crossed and some of which may have been expressed by both wheat varieties but now would be at a level equal to or greater than the level expressed in wheat variety W040511B1. The homozygous W040511B1-derived wheat plants have, on average, 50% of their genes derived from wheat variety W040511B1, but various individual plants from the population would have a much greater percentage of their alleles derived from W040511B1. The breeding process, of crossing, selfing, and selection may be repeated to produce another population of W040511B1-derived wheat plants with, on average, 25% of their genes derived from wheat variety W040511B1, and with various individual plants from the population having a much greater percentage of their alleles derived from W040511B1. Homozygous W040511B1-derived wheat plants that have received W040511B1-derived traits are also provided.
In some instances, selection may or may not occur at every selfing generation, selection may occur before or after the actual self-pollination process occurs, or individual selections may be made by harvesting individual spikes, plants, rows or plots at any point during the breeding process described herein. In addition, double haploid breeding methods may be used at any step in the process. In one aspect, the population of plants produced at each and any generation of selfing, each such population consisting of plants containing approximately 50% of its genes from wheat variety W040511B1, 25% of its genes from wheat variety W040511B1 in the second cycle of crossing, selfing, and selection, 12.5% of its genes from wheat variety W040511B1 in the third cycle of crossing, selfing, and selection, and so on.
Also disclosed are methods of obtaining a homozygous W040511B1-derived wheat plant by crossing wheat variety W040511B1 with another variety of wheat and applying double haploid methods to the F1 seed or F1 plant or to any generation of W040511B1-derived wheat obtained by the selfing of this cross.
Still further, methods for producing W040511B1-derived wheat plants are provided by crossing wheat variety W040511B1 with a wheat plant and growing the progeny seed, and repeating the crossing or selfing along with the growing steps with the W040511B1-derived wheat plant from 1 to 2 times, 1 to 3 times, 1 to 4 times, or 1 to 5 times. Thus, any and all methods using wheat variety W040511B1 in breeding, including selfing, pedigree breeding, backcrossing, hybrid production and crosses to populations are provided. Unique starch profiles, molecular marker profiles and/or breeding records can be used to identify the progeny lines or populations derived from these breeding methods.
Also disclosed are methods of harvesting the grain of variety wheat variety W040511B1 and using the grain as seed for planting. Embodiments include cleaning the seed, treating the seed, and/or conditioning the seed. Cleaning the seed includes removing foreign debris such as weed seed and removing chaff, plant matter, from the seed. Conditioning the seed can include controlling the temperature and rate of dry down and storing seed in a controlled temperature environment. Seed treatment is the application of a composition to the seed such as a coating or powder. Seed material can be treated, typically surface treated, with a composition comprising combinations of chemical or biological herbicides, herbicide safeners, pesticides, insecticides, fungicides, nutrients, germination inhibitors, germination promoters, cytokinins, nutrients, plant growth regulators, antimicrobials, and activators, bactericides, nematicides, avicides, or molluscicides. These compounds are typically formulated together with further carriers, surfactants or application-promoting adjuvants customarily employed in the art of formulation. The coatings may be applied by impregnating propagation material with a liquid formulation or by coating with a combined wet or dry formulation. Examples of the various types of compounds that may be used as seed treatments are provided in The Pesticide Manual: A World Compendium, C.D.S. Tomlin Ed., published by the British Crop Production Council. Some specific seed treatments that may be used on crop seed include, but are not limited to, abscisic acid, acibenzolar-S-methyl, avermectin, amitrol, azaconazole, azospirillum, azoxystrobin, bacillus, Bacillus subtilis, Bacillus simplex, Bacillus firmus, Bacillus amyloliquefaciens, Pasteuria genus (e.g. P. nishizawae), bradyrhizobium, captan, carboxin, chitosan, clothianidin, copper, cyazypyr, difenoconazole, etidiazole, fipronil, fludioxonil, fluquinconazole, flurazole, fluxofenim, GB126, Harpin protein, imazalil, imidacloprid, ipconazole, isofavenoids, lipo-chitooligosaccharide, mancozeb, manganese, maneb, mefenoxam, metalaxyl, metconazole, PCNB, penflufen, penicillium, penthiopyrad, permethrine, picoxystrobin, prothioconazole, pyraclostrobin, rynaxypyr, S-metolachlor, saponin, sedaxane, TCMTB, tebuconazole, thiabendaxole, thiamethoxam, thiocarb, thiram, tolclofos-methyl, triadimenol, trichoderma, trifloxystrobin, triticonazole and/or zinc.
It is routine practice to test seed varieties and seeds with specific genetic resistance traits to determine which seed treatment options and application rates will complement such varieties and genetic resistance traits in order to enhance yield. For example, a variety with good yield potential but loose smut susceptibility will benefit from the use of a seed treatment that provides protection against loose smut. Likewise, a variety encompassing a genetic resistance trait conferring insect resistance will benefit from the second mode of action conferred by the seed treatment. Further, the good root establishment and early emergence that results from the proper use of a seed treatment will result in more efficient nitrogen use, a better ability to withstand drought and an overall increase in yield potential of a variety or varieties containing a certain trait when combined with a seed treatment.
Methods for analyzing polynucleotides from plants, plant parts or seeds described herein may include contacting a polynucleotide from the plant, plant part or seed, such as from wheat variety W040511B1 with a molecular marker or with modified nucleotides that facilitate sequencing of the polynucleotide. The polynucleotide may be isolated, separated or otherwise obtained from the plant, plant part or seed. Modified nucleotides such as dNTPs may be incorporated with the polynucleotides along with appropriate primers in a reaction mixture that facilitates sequencing. Sequencing can be done using any method known in the art.
It will be apparent to those of skill in the art that variations may be applied to the compositions and methods described herein and in the steps or in the sequence of steps of the method described herein without departing from the concept, spirit and scope of the invention. More specifically, it will be apparent that certain changes and modifications such as single gene conversions, including for example, modifications and mutations, somoclonal variants, variant individuals selected from large populations of the plants of the instant inbred and the like may be practiced. All such similar substitutes and modifications apparent to those skilled in the art are deemed to be within the spirit, scope and concept of the invention.

Examples 2-13
Assays Performed to Develop W040511B1
The following examples provide descriptions of several assays that can be used to characterize and/or select a wheat variety during one or more stages of variety development. Many other methods and assays are available and can be substituted for, or used in combination with, one or more of the examples provided herein. Tables 1, 2, 3 and 4 provide further information on wheat variety W040511B1, which results may be produced from at least one or more assays or methods described in the following examples.
Example 2
Stripe Rust Screening
Stripe rust is a fungal leaf disease that is most common in the mid-southern United States in the early spring. Significant levels of the disease can be found in some seasons anywhere in North America. The infection often mostly occurs on the flag leaf but it may attack the entire plant, including the head. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance. Some major genes for resistance may be detected using controlled seedling screening experiments inoculated with specific races of the pathogen. There are also molecular markers for QTL linked to some specific resistance genes.
Example 3
Leaf Rust Screening
Leaf rust is a fungal leaf disease that is most common in the southern United States in the spring and early summer. Significant levels of the disease can be found in most seasons anywhere in North America. The infection is most damaging when it occurs on the flag leaf but it may attack the entire plant, including the head. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance. Some major genes for resistance may be detected using controlled seedling screening experiments inoculated with specific races of the pathogen. There are also molecular markers for QTL linked to some specific resistance genes.
Example 4
Leaf Blight Screening
Fungal leaf blights, including Tan spot, Septoria tritici blotch, and Stagnospora nodorum blotch, are common in much of the North American wheat growing regions. The infection is most damaging when it occurs on the flag leaf but it may attack the entire plant, including the head. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance.
Example 5
Scab Screening
Fusarium head blight or scab is a fungal disease that is common in much of the North American wheat growing regions. Infection occurs during flowering and is most severe when conditions are wet, warm and remain humid. The disease infects flowers on the spike and will spread to adjacent flowers, often infecting most of the developing kernels on the spike. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance. Infection may be induced in controlled screening experiments where spikes are inoculated with specific spore concentrations of the fungus by spraying the spikes at flowering or injecting the inoculum directly into a flower on each spike. There are also molecular markers for QTL linked to some specific resistance genes.
Example 6
Powdery Mildew Screening
Powdery mildew is a fungal leaf disease that is most common in the southern United States in the spring and early summer. Significant levels of the disease can be found in many seasons anywhere in North America. The infection is most damaging when it occurs on the flag leaf but it may attack the entire plant, including the head. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance. Some major genes for resistance may be detected using controlled seedling screening experiments inoculated with specific races of the pathogen. There are also molecular markers for QTL linked to some specific resistance genes.
Example 7
Soilborne Mosaic Virus Screening
Soilborne mosaic virus is transmitted by the vector, Polymyxa graminis, which tends to be most common in low-lying, wet soils; particularly those frequently grown to wheat. Symptoms appear in the spring as light green to yellow mottling along with stunting and resetting plant growth in the most susceptible varieties. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance. Higher levels of natural infection can be induced for screening by planting wheat annually in the same field to increase the vector level.
Example 8
Wheat Yellow (Spindle Streak) Mosaic Virus Screening
Wheat yellow virus is transmitted by the vector, Polymyxa graminis, and is most common during cool weather conditions in the spring. Symptoms appear as light green to yellow streaks and dashes parallel to the leaf veins. Symptoms often fade prior to heading as weather conditions become warmer. Natural infection of plants in the field may be rated visually using a 1-9 scale, where 1 indicates complete susceptibility and 9 indicates complete resistance.

Flour Yield Screening
The potential average flour yield of wheat can be determined on samples of grain that has been cleaned to standard and tempered to uniform moisture, using a test mill such as the Allis-Chalmers or Brabender mill. Samples are milled to established parameters, the flour sifted into fractions, which are then weighed to calculate flour yield as a percentage of grain weight.
Flour yield “as is” is calculated as the bran weight (over 40 weight) subtracted from the grain weight, divided by grain weight and times 100 to equal “as is” flour yield. Flour yield is calculated to a 15% grain moisture basis as follows: flour moisture is regressed to predict the grain moisture of the wheat when it went into the Quad Mill using the formula

Initial grain moisture=1.3429×(flour moisture)−4.

The flour yields are corrected back to 15% grain moisture after estimating the initial grain moisture using the formula

Flour Yield(15%)=Flour Yield(as is)−1.61%×(15%−Actual flour moisture)

Example 10
Flour Protein Screening
The protein content as a percentage of total flour may be estimated by the Kjeldahl method or properly calibrated near-infrared reflectance instruments to determine the total nitrogen content of the flour.
Flour protein differences among cultivars can be a reliable indicator of genetic variation provided the varieties are grown together, but can vary from year to year at any given location. Flour protein from a single, non-composite sample may not be representative. Based on the Soft Wheat Quality Laboratory grow-outs, protein can vary as much 1.5% for a cultivar grown at various locations in the same 1⁄2 acre field.
Example 11
Sucrose Solvent Retention Capacity (Src)
The solvent retention capacity (SRC) of wheat flour measures the ability of the flour to retain various solvents after centrifugation. Sucrose SRC predicts the starch damage and pentosan components, and can be correlated to sugar-snap cookie diameter quality metrics.
Sucrose SRC is a measure of arabinoxylans (also known as pentosans) content, which can strongly affect water absorption in baked products. Water soluble arabinoxylans are thought to be the fraction that most greatly increases sucrose SRC. Sucrose SRC probably is the best predictor of cookie quality, with sugar snap cookie diameters decreasing by 0.07 cm for each percentage point increase in sucrose SRC. The negative correlation between wire-cut cookie and sucrose SRC values is r=−0.66 (p<0.0001). Sucrose SRC typically increases in wheat samples with lower flour yield (r=−0.31) and lower softness equivalent (r=−0.23). The cross hydration of gliadins by sucrose also causes sucrose SRC values to be correlated to flour protein (r=0.52) and lactic acid SRC (r=0.62). Soft wheat flours for cookies typically have a target of 95% or less when used by the US baking industry for biscuits and crackers. Sucrose SRC values increase by 1% for every 5% increase in lactic acid SRC. The 95% target value can be exceeded in flour samples where a higher lactic acid SRC is required for product manufacture since the higher sucrose SRC is due to gluten hydration and not to swelling of the water soluble arabinoxylans.
Example 12
Lactic Acid Src
Lactic Acid SRC=Lactic Acid Solvent Retention Capacity. Lactic acid SRC measures gluten strength. Typical values are below 85% for “weak” soft varieties and above 105% or 110% for “strong” gluten soft varieties. See the above discussion of protein quality in this section for additional details of the lactic acid SRC. Lactic acid SRC results correlate to the SDS-sedimentation test. The lactic acid SRC is also correlated to flour protein concentration, but the effect is dependent on genotypes and growing conditions. The SWQL typically reports a protein-corrected lactic acid SRC value to remove some of the inherent protein fluctuation not due to cultivar genetics. Lactic acid is corrected to 9% protein using the assumption of a 7% increase in lactic acid SRC for every 1% increase in flour protein. On average across 2007 and 2008, the change in lactic acid SRC value was closer to 2% for every 1% protein.
