     Grain Set Under Bags. Grain set under bags is a measure of the self fertility of a plant. Pollinating bags are placed over the panicle prior to the initiation of flowering and remain in place until seed set can be determined, generally three weeks or more after flowering has been completed. At that time a percentage rating of seed set is made. This can range from 0% (indicating the plant is pollen sterile) to 100% (indicating full pollen fertility). Intermediate ratings can indicate varying levels of partial fertility.

     Height Uniformity. Height uniformity is a rating of the uniformity of the height of all of the main heads and tillers for a variety. 
     Leaf Attitude. Leaf attitude refers to an indicator of the attitude of the leaves with reference to the stalk, where “E” indicates erect (leaf angle [panicle to leaf axil to leaf midrib] less than about 45 degrees), “SE” indicates semi-erect (leaf angle of about 45-80 degrees), and “H” indicates horizontal (leaf angle of about 80 degrees or greater). 
     Leaf Color Intensity. The leaf color intensity is described as the color intensity from very light to very dark. 
     Leaf Length and Width. Leaf length and width is measured by selecting the largest leaf, after flowering, on a representative sample of plants and measuring the maximum length and width in inches. Generally, this will be a leaf towards the middle of the plant. 
     Leaf Number. Leaf number is measured by counting the total number of leaves on the plant after flowering. Some of the first leaves may have deteriorated by that time, so an estimate can be made. 
     Locus. A locus is the specific location of a gene or DNA sequence on a chromosome. 
     Maturity. The maturity of a variety is measured as the number of days between planting and physiological maturity. 
     Maize Dwarf Mosaic Virus (MDMV). MDMV refers to a visual rating of a variety&#39;s resistance to the Maize Dwarf Mosaic Virus, type “A.” 
     Mid-Rib Color. Mid-rib color can be described as white, cloudy, intermediate, or brown. White indicates a dry mid-rib and stalk, while cloudy indicates that they are juicy. Brown indicates the presence of a mutant allele that conditions for a reduced amount of lignin in the plant. 
     Panicle Appearance Rating. Panicle Appearance Rating is a rating of the overall panicle appearance that includes panicle type, panicle length, panicle diameter, grain color, grain color intensity, grain weathering, seed size, glume size, presence or absence of panicle diseases (i.e.  fusarium  head blight), and other criteria that may be important for a given environment. 
     Panicle Branch Attitude. Panicle branch attitude is an indicator of the attitude of the panicle branch with reference to the stalk, where “E” indicates erect (panicle branch angle [central rachis to panicle branch axil to panicle branch] less than about 45 degrees), “SE” indicates semi-erect (panicle branch angle of about 45-80 degrees), and “H” indicates horizontal (panicle branch angle of about 80 degrees or greater). 
     Panicle Blasting Percent. Panicle blasting percent is the percentage of florets in a panicle aborted by a  sorghum  plant. This data is usually recorded on cytoplasmic male sterile lines and is influenced by genotype and environment. Presence of this condition is a deleterious trait for commercial seed production. 
     Panicle Branch Length. Panicle Branch Length is measured by selecting panicle branches from the middle of the panicle, which are generally the longest, and measuring the length in inches. 
     Panicle Diameter. Panicle Branch Diameter is a measurement, in inches, of the largest part of the panicle at the stage when grain is fully mature. 
     Panicle (or Head) Exsertion. Panicle (or Head) Exsertion is a 1 to 9 rating representing the length of the peduncle exposed between the base of the panicle (head) and the flag leaf of the plant. A high score indicates more distance between the flag leaf and the  sorghum  head, while a low score indicates a short distance between the two. 
     Panicle Length. Panicle length is the length of the panicle, in inches, from the attachment point of the lowest branch to the tip of the uppermost branch in its normal orientation. 
     Panicle (or Head) Type. Panicle (or Head) Type is an indicator of the morphology of a  sorghum  plant&#39;s head (panicle), where “O” indicates an open panicle characterized by either more distance between the panicle branches or longer panicle branches; “SO” indicates a less open panicle; “SC” indicates a semi-compact panicle caused by shorter panicle branches arranged more closely on the central rachis; and “C” indicates a very compact panicle caused by very short panicle branches arranged tightly on the central rachis.

     Plant. As used herein, the term plant includes reference to an immature or mature whole plant, including a plant from which seed or grain or anthers have been removed. 
     Plant Color. Plant color results from the presence or absence of anthocyanin pigments in the stalks and other organs of  sorghum  plants. The type and degree of coloration is determined by genotype and is somewhat subject to growing conditions, but varieties typically show varying degrees of coloration ranging from: absent (tan plant) to very strong (deep purple coloration). Ratings generally are tan, red, or purple. 
     Plant Height. Plant height refers to the average height of the plant at the end of flowering, assuming the plant is not lodged. This varies from variety to variety and although it can be influenced by environment, relative comparisons between varieties grown side by side are useful for variety identification. Plant height is measured in inches, from the ground to the tip of the panicle. 
     Plant Parts. As used herein, the term plant parts (or “ sorghum  plant, or a part thereof”) includes, but is not limited to, protoplasts, leaves, stalks, roots, root tips, anthers, stigmas, panicles, seeds, grains, embryos, pollen, ovules, flowers, shoots, tissue, cells, and meristematic cells.

     Pre-Flower Stress Tolerance. Pre-flower stress tolerance is a visual rating of the stress tolerance of a  sorghum  plant before flowering. Symptoms that indicate poor pre-flower stress tolerance include poor panicle exertion, delayed panicle development, panicle exsertion, and flowering, and in extreme cases, abortion of the panicle. 
     Post-Flower Stress Tolerance. Post-flower stress tolerance is a rating of the stress tolerance of a  sorghum  plant after flowering. Symptoms that indicate poor post-flower stress tolerance include varying degrees of senescence of leaves starting with the lower leaves, pre-disposition and infection by stalk rot organisms such as Charcoal Rot ( Macrophomina phaseolina ), and varying degrees of stalk lodging. 
     Post-Freeze Standability. Post-freeze standability is a rating of the standability of a  sorghum  plant after a freeze. 
     Regeneration. Regeneration refers to the development of a plant from tissue culture. 
     Relative Maturity. Relative maturity (RM) for a variety is based on the predicted number of days required for an inbred line or hybrid to reach the blooming stage from the time of planting. The RM rating is relative to a set of known check varieties and is determined using standard linear regression analysis. 
     Resistance to Lodging. Resistance to lodging is a visual rating (relative to check varieties) of a variety&#39;s ability to stand up in the field under high yield conditions and severe environmental factors. A variety can have good (remains upright), fair, or poor (falls over) resistance to lodging. The degree of resistance to lodging is not expressed under all conditions but is most meaningful when there is some degree of lodging in a field trial. 
     Root Lodging. Root lodging is the percentage of lodged plants of a variety caused by an inadequate root support system. If the stem of the plant leans at an angle of approximately 30 degrees or more from vertical, the plant is considered to be root lodged. 
     Seed Coat Color. The color of the seed coat can be variety-specific and can be red, brown, white, or yellow for inbred lines. For hybrids, the seed coat color may also be cream (from a white×yellow cross) and bronze (from a red×yellow cross). 
     Seeds per Pound. Seeds per pound refers to the number of seeds per pound of grain for a representative sample. 
     Seedling Vigor. Seedling vigor is a visual rating of the amount of vegetative growth. The rating is usually taken when the average entry in the trial is at the two- to three-leaf stage. 
     Selection Index. The selection index provides a single measure of a variety&#39;s performance based on a composite of multiple traits. A  sorghum  breeder may utilize his or her own set of traits for the selection index. Two of the traits usually included are yield and days to flower (relative maturity). The selection index data presented herein represent the mean values averaged across testing locations. 
     Single Gene Converted (Conversion). Single gene conversion or a single gene converted plant refers to plants that are developed by backcrossing, genetic engineering, or mutation, wherein essentially all of the desired morphological and physiological characteristics of a variety are recovered, in addition to the single gene transferred into the variety via the backcrossing technique, genetic engineering, or mutation. 
       Sorghum  Midge Resistance.  Sorghum  Midge Resistance refers to a visual rating of a variety&#39;s resistance to  sorghum  midge, an insect pest that affects seed set by infecting the head. 
     Stalk Lodging. Stalk lodging refers to the percentage of lodged plants of a variety caused by stalks breaking above the ground due to natural causes. 
     Staygreen. Staygreen refers to a visual rating of a variety&#39;s ability to retain green leaf tissue. Ratings are most valuable in the presence of heat and/or drought stress during the grain fill period. 
     Testweight. Testweight is a measure of the weight (in pounds) of the grain harvested from a variety for a given volume (bushel), adjusted to a standard grain moisture content. 
     Threshability. Threshability refers to a visual rating (relative to check varieties) of the tendency of the seed of a variety to thresh free from the glumes. 
     Tillering. Tillering is a measure of the development of shoots from buds at the base of the main stem. This can be expressed as a visual rating (on a scale of 1 to 9, with 1 being a high degree of tillering and 9 being no tillering. This can also be expressed as an actual number of tillers per plant. 
     Tissue Culture. Tissue culture encompasses all cultural techniques in which a composition comprising embryonic issues, tissue fragments, calli, isolated cells or protoplasts of the same or a different type, or a collection of such cells are organized into a culture for the regeneration of functional plants or plant parts. 
     Yield. This term refers to the actual yield (measured in pounds per acre) of the grain harvested from a unit area for a variety, adjusted to a standard 13% grain moisture content. 
     Yield Under Stress. Yield under stress is a rating of the yield of grain harvested from a unit area when such unit area is under stress, for example, from drought or heat. This can be determined by comparing the points where regression lines intersect the y axis for different hybrids when yield for the individual hybrids is regressed against the average yield for all hybrids in the tests. A high value for y axis intercept indicates a drought and stress tolerant hybrid whereas a low value indicates poor drought and stress tolerance. 
     Reference now will be made in detail to the embodiments of the invention, one or more examples of which are set forth below. Each example is provided by way of explanation of the invention, not a limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment, can be used on another embodiment to yield a still further embodiment. 
     Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents. Other objects, features and aspects of the present invention are disclosed in or are obvious from the following detailed description. It is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only, and is not intended as limiting the broader aspects of the present invention. 
       Sorghum  plants ( sorghum bicolor  (L.)  Moench ) have both male (anthers) and female (stigma) reproductive parts located in the same flower in the panicle. Natural pollination occurs in  sorghum  when anthers shed pollen and pollen falls onto receptive stigmata. Because of the close proximity of the anthers and stigmata in the panicle, the rate of self pollination is very high (average 94%). 
     In an embodiment, the present invention relates to a  sorghum  plant of the variety designated GSV548207. The inbred  sorghum  plant variety designated GSV548207 was derived from an initial cross between the lines GSV986142 and GSV253175. The origin and breeding history of the  sorghum  variety designated GSV548207 can be summarized as follows: 
     Summer 2002 at Plainview, Tex. The inbred line GSV986142 (a proprietary Monsanto Company inbred) was crossed to the inbred line GSV253175 (a proprietary Monsanto Company inbred) using a wet pollen emasculation between nursery rows E1591 and E1593 to produce an F1. 
     Winter 2002-2003 in Puerto Rico. The F1 was grown and self pollinated using open pollination in nursery row F1-244 to produce F2 seed. 
     Summer 2003 at Mt. Hope, Kans. The F2 was grown in nursery row F2-1063. It was self pollinated using open pollination and the F3 selection was made. In this and in subsequent selection opportunities yield, stalk quality, root quality, disease tolerance, pollen shedding ability, insect tolerance, plant height, head exsertion, and stress tolerance were some of the criteria used to determine which plants were selected. 
     Summer 2004 at Mt. Hope, Kans. The F3 was grown in nursery row F3-1287. It was self pollinated using open pollination and the F4 selection was made. 
     Summer 2005 at Lubbock, Tex. The F4 was grown in nursery row 05 06 41 41 TXLUNURB — 00025 — 00081 — 1_. It was self pollinated using open pollination and the F5 selection was made. 
     Winter 2006-2007 in San Juan de Abajo, Mexico. The F5 was grown in nursery row 06 12 92 92 JAPVNURS4 — 00010 — 00004 — 1_. It was self pollinated and the F6 selection was made. 
     Summer 2007 at Mt. Hope, Kans. The F6 was grown in nursery row 07 04 92 92 KSMH3B — 00019 — 00005 — 1_. It was self pollinated and the F7 selection was made. 
     Winter 2007-2008 at San Juan de Abajo, Mexico. The F7 was grown in nursery row 07 12 92 92 JAPV3 — 00043 — 00022 — 1_. It was self pollinated and the F8 selection was made. 
     Summer 2008 at Mt. Hope, Kans. The F8 was grown in nursery row 08 04 92 92 KSMH3A — 00010 — 00006 — 1_. It was self pollinated and the F9 selection was made. 
     Winter 2008-2009 in San Juan de Abajo, Mexico. The F9 was grown in nursery row 08 12 92 92 JAPV3A — 00022 — 00011 — 1_. It was self pollinated and the F10 selection was made. Line coded in March 2009 as GSV548207. 
     Summer 2009 at Mt. Hope, Kans. The F10 was grown in nursery row 09 04 92 92 KSMH1 — 00019 — 00023_@_. It was self pollinated and the F11 seed was bulked. 
     Winter 2009-2010 in San Juan de Abajo, Mexico. The F10 derived bulk in the F11 was grown in 30 nursery rows with the row source designation of 09 12 92 92 JAPVBLK5 — 00029 — 00076_@_. It was bagged and self pollinated and sufficient bulk seed was generated (an F10 derived bulk in the F12) to plant a seedstock increase and a pilot hybrid production block in 2010. Seed increases from that point forward were conducted by the production department. 
     In an embodiment, the invention relates to  sorghum  plants having all or essentially all of the physiological and morphological characteristics of the inbred  sorghum  variety GSV548207. In an embodiment, the physiological and morphological characteristics of the inbred  sorghum  variety are set forth in Table 1.  sorghum  variety GSV548207 has shown acceptable levels of uniformity and stability, within the limits of environmental influence, for the traits described in Table 1.  sorghum  variety GSV548207 has been self-pollinated and head-rowed a sufficient number of generations to ensure homozygosity and phenotypic stability. In certain categories of variety description information, GSV548207 has been compared to  sorghum  varieties TX2737 and OK11.

     In an embodiment, the GSV548207  sorghum  plants of the invention are inbred. Inbred GSV548207  sorghum  plants can be produced by planting the seeds of the inbred  sorghum  plant designated GSV548207 and growing the resulting  sorghum  plants under self-pollinating or sib-pollinating conditions with adequate isolation, using standard techniques well known to an artisan skilled in the agricultural arts. 
     In a particular embodiment, the present invention provides a method of producing an inbred  sorghum  plant derived from the  sorghum  variety designated GSV548207, the method comprising the steps of: (a) preparing a progeny plant derived from  sorghum  variety GSV548207, wherein said preparing comprises crossing a plant of the  sorghum  variety GSV548207 with a second  sorghum  plant; (b) crossing the progeny plant with itself or a second plant to produce a seed of a progeny plant of a subsequent generation; (c) growing a progeny plant of a subsequent generation from said seed of a progeny plant of a subsequent generation and crossing the progeny plant of a subsequent generation with itself or a second plant; and (d) repeating the steps for an additional 3 to 10 generations to produce an inbred  sorghum  plant derived from the  sorghum  variety GSV548207. In the method, it may be desirable to select particular plants resulting from step (c) for continued crossing according to steps (b) and (c). By selecting plants having one or more desirable traits, an inbred  sorghum  plant derived from the  sorghum  variety GSV548207 may be obtained which possesses some or essentially all of the desirable traits of  sorghum  variety GSV548207 as well as potentially other selected traits. In a particular embodiment, the invention comprises an elite GSV548207  sorghum  parent plant or line. 
     In yet another embodiment, the invention is directed to parts of the GSV548207  sorghum  plant. Any part of the GSV548207  sorghum  plant is contemplated in this embodiment. In an embodiment, the plant part may comprise pollen obtained from a GSV548207  sorghum  plant. In still another embodiment, the invention comprises seed of the GSV548207  sorghum  plant. Seeds can be harvested from a GSV548207 plant using standard, well-known procedures. 
     In an embodiment, the seeds are inbred GSV548207 seeds. Inbred  sorghum  seed of the invention may be provided as an essentially homogeneous population of inbred  sorghum  seed of the variety designated GSV548207. Essentially homogeneous populations of inbred seed may be free from substantial numbers of seeds that are significantly different on a genetic basis. In an embodiment of the present invention, inbred seed may form greater than about 97% of the total seed. In an embodiment, the population of inbred  sorghum  seed of the invention may be essentially free from hybrid seed. In some embodiments, the inbred seed population may be grown separately from any hybrid population to provide an essentially homogeneous population of inbred  sorghum  plants designated GSV548207. 
     In yet another embodiment of the invention, a tissue culture of regenerable cells of a plant of the variety designated GSV548207 is provided. The regenerable cells in such tissue cultures may be derived from embryos, meristematic cells, microspores, pollen, anthers, stigma, flowers, leaves, stalks, roots, root tips, seeds, or from callus or protoplasts derived from those tissues. Means for preparing and maintaining plant tissue cultures are well known in the art. 
     In an embodiment, the tissue culture may be capable of regenerating plants capable of expressing essentially all of the physiological and morphological characteristics of the GSV548207 variety, and of regenerating plants having substantially the same genotype as other plants of the GSV548207 variety. Still further, the present invention provides  sorghum  plants regenerated from the tissue cultures of the invention, the plants having all or essentially all of the physiological and morphological characteristics of the variety designated GSV548207. 
     In a particular embodiment, the invention relates to a  sorghum  hybrid containing the  sorghum  variety GSV548207. A  sorghum  hybrid is the cross of two inbred lines, each of which may have one or more desirable characteristics lacked by the other and/or which complement the other. As used herein, crossing can include selfing, backcrossing, crossing to another or the same inbred, crossing to populations, and the like. 
     In an embodiment, the  sorghum  plants can be crossed by either natural or mechanical techniques. Natural pollination occurs in  sorghum  when wind blows pollen from the anthers to receptive stigmata on the same or another plant. Mechanical pollination can be effected either by controlling the types of pollen that can blow onto the receptive stigmata or by pollinating by hand. These techniques are well known in the art. 
     Because  sorghum  is normally a self-pollinated plant and because both male and female flowers are in the same panicle, a cytoplasmic male sterile (CMS) inbred may be used to produce large quantities of hybrid seed. Cytoplasmic-male sterility is a pollen abortion phenomenon determined by the interaction between the genes in the cytoplasm and the nucleus. Alteration in the mitochondrial genome and the lack of restorer genes in the nucleus will lead to pollen abortion. With either a normal cytoplasm or the presence of restorer gene(s) in the nucleus, the plant will produce pollen normally. A CMS plant can be pollinated by a maintainer version of the same variety, which has a normal cytoplasm but lacks the restorer gene(s) in the nucleus, and will continue to be male sterile in the next generation. The male fertility of a CMS plant can be restored in the subsequent generation by crossing it with a plant that contains the restorer gene(s) in the nucleus. With the restorer gene(s) in the nucleus, the offspring of the male-sterile plant can produce normal pollen grains and propagate. Thus, in a hybrid seed production system, flowers of a CMS inbred (non-restorer female parent) may be fertilized with pollen from a fertile inbred (restorer male parent) carrying genes which restore male fertility in the hybrid (F 1 ) progeny. 
     The development of a  sorghum  hybrid, in an embodiment, may involve the following steps: (1) the formation of “restorer” and “non-restorer” germplasm pools; (2) the selection of superior plants from various “restorer” and “non-restorer” germplasm pools; (3) the selfing of the superior plants for one or more generations to produce a series of inbred lines, which although different from each other, breed true and are highly uniform; (4) the conversion of inbred lines classified as females or non-restorers to CMS forms; and (5) crossing the selected CMS female inbred lines with selected fertile male inbred lines to produce the hybrid progeny (F 1 ). 
     In another embodiment, the development of a  sorghum  hybrid may involve the steps of: (1) planting in pollinating proximity seeds of a first and second parent  sorghum  plant (the first and second plant may be distinct inbred plants); (2) cultivating or growing the seeds of the first and second parent  sorghum  plants into plants that bear flowers; (3) emasculating the flowers of either the first or second parent  sorghum  plant, i.e. physically removing the anthers from the florets prior to blooming of the flowers so as to prevent pollen production or preventing dehiscence of pollen from anthers by introduction and maintenance of a high humidity environment by bagging a panicle or portion of a panicle with a plastic bag prior to blooming (a “wet pollination emasculation”) or by using as the female parent a male sterile plant, thereby providing an emasculated parent  sorghum  plant; (4) allowing natural cross-pollination to occur between the first and second parent  sorghum  plants or mechanically moving pollen from the pollen parent to the pollen sterile seed parent; (5) harvesting seeds produced on the emasculated parent  sorghum  plant; and, where desired, (6) growing the harvested seed into a  sorghum  plant, which may be a hybrid  sorghum  plant. 
     In one embodiment, the  sorghum  hybrid containing the variety GSV548207 is a single cross hybrid. A single cross  sorghum  hybrid is the cross of two inbred plants, each of which has a genotype that complements the genotype of the other. In this embodiment, the F 1  hybrid may be more vigorous than its inbred parents. This hybrid vigor, or heterosis, may be manifested in many polygenic traits, including markedly improved yields, better stalks, better roots, better uniformity and better insect and disease resistance. 
     In an embodiment of the invention, either the first or second parent  sorghum  plants can be from variety GSV548207. Thus, any  sorghum  plant produced using  sorghum  plant GSV548207 forms a part of the invention. In an embodiment, the parent  sorghum  plants may be of different varieties. In still another embodiment, the invention comprises an elite hybrid containing the GSV548207  sorghum  plant or line. 
       Sorghum  lines are known to those of skill in the art, any one of which could be crossed with  sorghum  plant GSV548207 to produce a hybrid plant. The hybrid containing the GSV548207  sorghum  plant of the invention may be an F 1  hybrid, an F 2  hybrid, an F 3  hybrid, an F 4  hybrid, an F 5  hybrid, an F 6  hybrid, an F 7  hybrid, or any further generation hybrid. 
     An example of an F 1  hybrid which has been produced with GSV548207 as a parent is the hybrid G4282. Hybrid G4282 was produced by crossing inbred  sorghum  plant GSV548207 with the inbred  sorghum  plant designated GSV415986.

     In another embodiment of the invention, a plant of  sorghum  variety designated GSV548207 comprising an added heritable trait is provided. The heritable trait may comprise a genetic locus that is a dominant or recessive allele. When introduced through transformation, a genetic locus may comprise one or more transgenes integrated at a single chromosomal location. In one embodiment of the invention, a plant of  sorghum  variety GSV548207 comprising a single locus conversion in particular is provided. In specific embodiments of the invention, an added genetic locus confers one or more additional traits. The traits conferred may include, but are not limited to, male sterility, male fertility, herbicide tolerance or resistance, insect tolerance or resistance, disease tolerance or resistance, fungal tolerance or resistance, waxy starch, enhanced nutritional quality, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism. 
     In an embodiment, the trait may be cytoplasmically-inherited and may be passed to progeny through the female parent in a particular cross. An exemplary cytoplasmically-inherited trait is the male sterility trait. A cytoplasmically-inherited trait may be a naturally-occurring  sorghum  trait or a trait introduced through genetic transformation techniques. 
     In other embodiments, the trait may be conferred by a naturally-occurring  sorghum  gene introduced into the genome of the variety designated GSV548207 by backcrossing, a natural or induced mutation, or a transgene introduced through genetic transformation techniques. If backcrossing is used in an embodiment, essentially all of the desired morphological and physiological characteristics of a variety may be recovered in addition to a genetic locus transferred into the plant via the backcrossing technique. 
     In a backcross procedure, the parental  sorghum  plant which contributes the locus or loci for the desired trait is typically termed the non-recurrent or donor parent. This terminology refers to the fact that the non-recurrent parent is used one time in the backcross protocol and, therefore, does not reoccur. 
     The parental  sorghum  plant to which the locus or loci from the non-recurrent parent are transferred is known as the recurrent parent, as it is used for several rounds in the backcrossing protocol. In a typical backcross protocol, the original parent of interest (recurrent parent) is crossed to a second variety (non-recurrent parent) that carries the genetic locus of interest to be transferred. The resulting progeny from this cross are then crossed again to the recurrent parent and the process is repeated until a  sorghum  plant is obtained wherein essentially all of the desired morphological and physiological characteristics of the recurrent parent are recovered in the converted plant, in addition to the transferred locus from the non-recurrent parent. The backcross process may be accelerated by the use of genetic markers, such as single sequence repeat (SSR), restriction fragment length polymorphism (RFLP), single nucleotide polymorphism (SNP) or amplified fragment length polymorphism (AFLP) markers to identify plants with the greatest genetic complement from the recurrent parent. 
     The selection of a suitable recurrent parent is an important step for a successful backcrossing procedure. The choice of the particular non-recurrent parent will depend on the purpose of the backcross. One of the major purposes is to add commercially desirable, agronomically important traits to the plant. The exact backcrossing protocol will depend on the characteristic or trait being altered to determine an appropriate testing protocol. Although backcrossing methods are simplified when the characteristic being transferred is a dominant allele, a recessive allele may also be transferred. In this instance it may be necessary to introduce a test of the progeny to determine which progeny carry the desired allele. 
     As part of the invention, direct selection may be applied where a genetic locus acts as a dominant trait. An example of a dominant trait may be a herbicide resistance trait, which, in some cases, is inherited in a dominant fashion. For this selection process, the progeny of the initial cross may be sprayed with the herbicide prior to the backcrossing. The spraying eliminates any plants which do not have the desired herbicide resistance characteristic, and only those plants that have the herbicide resistance gene are used in the subsequent backcross. This process is then repeated for all additional backcross generations. 
     It will be understood by those of skill in the art that a transgene need not be directly transformed into a GSV548207 plant, as techniques for the production of stably transformed  sorghum  plants that pass single loci to progeny by Mendelian inheritance are known in the art. Such loci may, therefore, be passed from parent plant to progeny plants by standard plant breeding techniques that are well known in the art. Examples of traits that may be introduced into a GSV548207  sorghum  plant according to the invention are provided below. 
     A. Male Sterility 
     In an embodiment, a male sterility trait is introduced into a GSV548207  sorghum  plant. Any gene conferring male sterility may be utilized in this embodiment. In a particular embodiment, the male sterility gene may be herbicide-inducible. Male sterility genes may increase the efficiency with which hybrids are made, in that they eliminate the need to physically emasculate the  sorghum  plant used as a female in a given cross. 
     Where the employment of male-sterility systems is desired with a  sorghum  plant in accordance with the invention, it may be beneficial to also utilize one or more male-fertility restorer genes. For example, where CMS is used, hybrid seed production requires three inbred lines: (1) a CMS female parent line having a CMS cytoplasm and possessing no restorer genes (also known as an “A” line); (2) a fertile inbred with normal cytoplasm that possesses no restorer genes, which is isogenic with the CMS line for nuclear genes (also known as a “maintainer line” or “B line”); and (3) a distinct, fertile, male parent line with normal cytoplasm, carrying fertility restorer genes (also known as the “restorer line” or “R line”). The CMS female parent line is propagated by pollination with the maintainer line, with all of the progeny being male sterile, as the CMS cytoplasm is derived from the female parent. These male sterile plants can then be employed as the female parent in hybrid crosses with the male restorer parent, without the need for physical emasculation of the male reproductive parts of the female parent. 
     The presence of a male-fertility restorer gene in the male parent results in the production of fully fertile F 1  hybrid progeny. If no restorer gene is present in the male parent, male-sterile hybrids are obtained. Such hybrids are useful where the vegetative tissue of the  sorghum  plant is utilized, e.g., for silage, but in most cases, the seeds will be deemed the most valuable portion of the crop. In these cases, fertility of the hybrids in these crops must be restored. Therefore, one aspect of the current invention concerns plants of the  sorghum  variety GSV548207 comprising a genetic locus capable of restoring male fertility in an otherwise male-sterile plant. Examples of male-sterility genes and corresponding restorers which could be employed with the plants of the invention are known to those of skill in the art of plant breeding. 
     B. Herbicide Resistance or Tolerance 
     In an embodiment, a herbicide resistance or tolerance trait is introduced into a GSV548207  sorghum  plant. Any gene conferring herbicide resistance or tolerance may be utilized in this embodiment. In an embodiment, the herbicide resistance or tolerance is for glyphosate, sulfonylurea, imidazalinone, dicamba, glufosinate, phenoxy proprionic acid, cycloshexone, triazine, benzonitrile, broxynil, quizalofop, nicosulfuron, acetolactate synthase-inhibiting herbicides, or 1-aminocyclopropane-1-carboxylic acid-inhibiting herbicides. Numerous herbicide resistance genes are known and may be employed with the invention. 
     C. Waxy Starch 
     In an embodiment, a waxy starch trait is introduced into a GSV548207  sorghum  plant. Any gene conferring waxy starch characteristics may be utilized in this embodiment. The waxy characteristic is an example of a recessive trait. In this example, the progeny resulting from the first backcross generation (BC1) may be grown and selfed. A test may then be run on the selfed seed from the BC1 plant to determine which BC1 plants carried the recessive gene for the waxy trait. 
     D. Disease Resistance or Tolerance 
     In an embodiment, a disease resistance or tolerance trait is introduced into a GSV548207  sorghum  plant. Any gene conferring disease resistance or tolerance may be utilized in this embodiment. In an embodiment, the gene may confer disease resistance to downy mildew, pathotypes 1, 3, or 6; maize dwarf mosaic virus “A”; head smut, race 1; charcoal rot; or  fusarium  head blight. In an embodiment, the disease may be a viral disease. 
     E. Insect Resistance or Tolerance 
     In an embodiment, an insect resistance or tolerance trait is introduced into a GSV548207  sorghum  plant. Any gene conferring insect resistance or tolerance may be utilized in this embodiment. In an embodiment, such gene may confer resistance to greenbug, biotype C, E, or I; chinch bug; or  sorghum  midge. 
     F. Modified Phytate and Carbohydrate Metabolism 
     In an embodiment, a trait that confers modified phytate or carbohydrate metabolism is introduced into a GSV548207  sorghum  plant. Any gene conferring modified phytate or carbohydrate metabolism may be utilized in this embodiment. For example, phytate metabolism may be modified by introduction of a phytase-encoding gene to enhance breakdown of phytate, adding more free phosphate to the transformed plant. A number of genes that may be used to alter carbohydrate metabolism are well known in the art. 
     G. Origin and Breeding History of an Exemplary Introduced Trait 
     GSV548413 A is a conversion of GSV548413 to cytoplasmic male sterility. GSV548413 A was derived using backcross methods. GSV548413 (a proprietary inbred of Monsanto Company) was used as the recurrent parent and GSV160919, a germplasm source carrying A1 cytoplasmic sterility, was used as the non-recurrent parent. The breeding history of the converted inbred GSV548413 A can be summarized as follows:

     H. Illustrative Procedures for Introduction of a Desired Trait 
     As described above, techniques for the production of  sorghum  plants with added traits are known in the art. An example of such a procedure for preparation of a  sorghum  plant of GSV548207 comprising an added trait is as follows:
         (a) crossing  sorghum  plant GSV548207 to a second (non-recurrent)  sorghum  plant comprising a locus to be converted in  sorghum  plant GSV548207;   (b) selecting at least a first progeny plant resulting from the crossing and comprising the locus;   (c) crossing the selected progeny to  sorghum  plant GSV548207; and   (d) repeating steps (b) and (c) until a plant of variety GSV548207 is obtained comprising the locus.       

     Following these steps, essentially any locus may be introduced into  sorghum  variety GSV548207. For example, molecular techniques allow introduction of any given locus, without the need for phenotypic screening of progeny during the backcrossing steps. Polymerase chain reaction (PCR) and Southern hybridization are two examples of molecular techniques that may be used for confirmation of the presence of a given locus and thus conversion of that locus. 
     The present invention additionally provides, in an embodiment, processes of preparing GSV548207  sorghum  plants. In accordance with such an embodiment, a first parent  sorghum  plant may be crossed with a second parent  sorghum  plant wherein at least one of the first and second  sorghum  plants is the inbred  sorghum  plant GSV548207. One application of the process is in the production of F 1  hybrid plants. Another important aspect of this process is that it can be used for the development of novel inbred lines. For example, the inbred  sorghum  plant GSV548207 could be crossed to any second plant and the resulting hybrid progeny each selfed for about 5 to 7 or more generations, thereby providing a large number of distinct, pure-breeding inbred lines. These inbred lines could then be crossed with other inbred or non-inbred lines and the resulting hybrid progeny analyzed for beneficial characteristics. In this way, novel inbred lines conferring desirable characteristics could be identified. After at least five or more generations, the inbred plant is typically considered genetically pure. Thus, in an embodiment, the invention comprises genetically pure inbred lines produced from the inbred  sorghum  plant GSV548207. 
     In a particular embodiment of the invention, the genetic complement of the  sorghum  plant variety designated GSV548207 is provided. A genetic complement represents the genetic make up of an inbred cell, tissue or plant. A hybrid genetic complement represents the genetic make up of a hybrid cell, tissue or plant. The invention thus provides  sorghum  plant cells that have a genetic complement in accordance with the inbred  sorghum  plant cells disclosed herein, and plants, seeds and diploid plants containing such cells. 
     In still another embodiment, the present invention provides hybrid genetic complements, as represented by  sorghum  plant cells, tissues, plants, and seeds, formed by the combination of a haploid genetic complement of an inbred  sorghum  plant of the invention with a haploid genetic complement of a second  sorghum  plant, which may be another, distinct inbred  sorghum  plant. In another aspect, the present invention provides a  sorghum  plant regenerated from a tissue culture that comprises a hybrid genetic complement of this invention. 
     Plant genetic complements may be assessed by genetic marker profiles, and by the expression of phenotypic traits that are characteristic of the expression of the genetic complement, e.g., isozyme typing profiles. It is understood that the  sorghum  variety designated GSV548207 could be identified by any of the many known techniques such as, for example, Simple Sequence Length Polymorphisms, Randomly Amplified Polymorphic DNAs, DNA Amplification Fingerprinting, Sequence Characterized Amplified Regions, Arbitrary Primed Polymerase Chain Reaction, AFLPs, and SNPs. 
     A genetic marker profile of an inbred may be predictive of the agronomic traits of a hybrid produced using that inbred. For example, if an inbred of known genetic marker profile and phenotype is crossed with a second inbred of known genetic marker profile and phenotype it is possible to predict the phenotype of the F 1  hybrid based on the combined genetic marker profiles of the parent inbreds. Methods for prediction of hybrid performance from genetic marker data are known in the art. Such predictions may be made using any suitable genetic marker, for example, SSRs, RFLPs, AFLPs, SNPs, or isozymes. 
     SSRs are genetic markers based on polymorphisms in repeated nucleotide 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 PCR, thereby eliminating the need for labor-intensive Southern hybridization. PCR detection is conducted using two oligonucleotide primers flanking the polymorphic segment of repetitive DNA. Repeated cycles 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 (number of base pairs) of the amplified segment. 
     In another embodiment of the invention, the method relates to the production of a GSV548207  sorghum  plant product.
