ALEXANDRIA, Virginia , August 23, 2013 (Biotech Week) – A patent by the inventor Hancock, Floyd (Stuttgart, AR), filed on February 2, 2011, was published online on August 13, 2013, according to news reporting originating from Alexandria, Virginia, by NewsRx correspondents (see also Biotechnology Companies).

Patent number 8507764 is assigned to Monsanto Technology LLC (St. Louis, MO).

The following quote was obtained by the news editors from the background information supplied by the inventors: "The present invention relates generally to the field of soybean breeding. In particular, the invention relates to the novel soybean variety A1023705.

"There are numerous steps 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 important traits may include higher seed yield, resistance to diseases and insects, better stems and roots, tolerance to drought and heat, better agronomic quality, resistance to herbicides, and improvements in compositional traits.

"Soybean, Glycine max (L.), is a valuable field crop. Thus, a continuing goal of plant breeders is to develop stable, high yielding soybean varieties that are agronomically sound. The reasons for this goal are to maximize the amount of grain produced on the land used and to supply food for both animals and humans. To accomplish this goal, the soybean breeder must select and develop soybean plants that have the traits that result in superior varieties."

In addition to the background information obtained for this patent, NewsRx journalists also obtained the inventor's summary information for this patent: "One aspect of the present invention relates to seed of the soybean variety A1023705. The invention also relates to plants produced by growing the seed of the soybean variety A1023705, as well as the derivatives of such plants. Further provided are plant parts, including cells, plant protoplasts, plant cells of a tissue culture from which soybean plants can be regenerated, plant calli, plant clumps, and plant cells that are intact in plants or parts of plants, such as pollen, flowers, seeds, pods, leaves, stems, and the like.

"Another aspect of the invention relates to a tissue culture of regenerable cells of the soybean variety A1023705, as well as plants regenerated therefrom, wherein the regenerated soybean plant is capable of expressing all the physiological and morphological characteristics of a plant grown from the soybean seed designated A1023705.

"Yet another aspect of the current invention is a soybean plant comprising a single locus conversion of the soybean variety A1023705, wherein the soybean plant is otherwise capable of expressing all the physiological and morphological characteristics of the soybean variety A1023705. In particular embodiments of the invention, the single locus conversion may comprise a transgenic gene which has been introduced by genetic transformation into the soybean variety A1023705 or a progenitor thereof. In still other embodiments of the invention, the single locus conversion may comprise a dominant or recessive allele. The locus conversion may confer potentially any trait upon the single locus converted plant, including herbicide resistance, insect resistance, resistance to bacterial, fungal, or viral disease, male fertility or sterility, and improved nutritional quality.

"Still yet another aspect of the invention relates to a first generation (F.sub.1) hybrid soybean seed produced by crossing a plant of the soybean variety A1023705 to a second soybean plant. Also included in the invention are the F.sub.1 hybrid soybean plants grown from the hybrid seed produced by crossing the soybean variety A1023705 to a second soybean plant. Still further included in the invention are the seeds of an F.sub.1 hybrid plant produced with the soybean variety A1023705 as one parent, the second generation (F.sub.2) hybrid soybean plant grown from the seed of the F.sub.1 hybrid plant, and the seeds of the F.sub.2 hybrid plant.

"Still yet another aspect of the invention is a method of producing soybean seeds comprising crossing a plant of the soybean variety A1023705 to any second soybean plant, including itself or another plant of the variety A1023705. In particular embodiments of the invention, the method of crossing comprises the steps of a) planting seeds of the soybean variety A1023705; b) cultivating soybean plants resulting from said seeds until said plants bear flowers; c) allowing fertilization of the flowers of said plants; and, d) harvesting seeds produced from said plants.

"Still yet another aspect of the invention is a method of producing hybrid soybean seeds comprising crossing the soybean variety A1023705 to a second, distinct soybean plant which is nonisogenic to the soybean variety A1023705. In particular embodiments of the invention, the crossing comprises the steps of a) planting seeds of soybean variety A1023705 and a second, distinct soybean plant, b) cultivating the soybean plants grown from the seeds until the plants bear flowers; c) cross pollinating a flower on one of the two plants with the pollen of the other plant, and d) harvesting the seeds resulting from the cross pollinating.

"Still yet another aspect of the invention is a method for developing a soybean plant in a soybean breeding program comprising: obtaining a soybean plant, or its parts, of the variety A1023705; and b) employing said plant or parts as a source of breeding material using plant breeding techniques. In the method, the plant breeding techniques may be selected from the group consisting of recurrent selection, mass selection, bulk selection, backcrossing, pedigree breeding, genetic marker-assisted selection and genetic transformation. In certain embodiments of the invention, the soybean plant of variety A1023705 is used as the male or female parent.

"Still yet another aspect of the invention is a method of producing a soybean plant derived from the soybean variety A1023705, the method comprising the steps of: (a) preparing a progeny plant derived from soybean variety A1023705 by crossing a plant of the soybean variety A1023705 with a second soybean plant; and (b) crossing the progeny plant with itself or a second plant to produce a progeny plant of a subsequent generation which is derived from a plant of the soybean variety A1023705. In one embodiment of the invention, the method further comprises: © crossing the progeny plant of a subsequent generation with itself or a second plant; and (d) repeating steps (b) and © for, for example, at least 2, 3, 4 or more additional generations to produce an inbred soybean plant derived from the soybean variety A1023705. Also provided by the invention is a plant produced by this and the other methods of the invention.

"In another embodiment of the invention, the method of producing a soybean plant derived from the soybean variety A1023705 further comprises: (a) crossing the soybean variety A1023705-derived soybean plant with itself or another soybean plant to yield additional soybean variety A1023705-derived progeny soybean seed; (b) growing the progeny soybean seed of step (a) under plant growth conditions, to yield additional soybean variety A1023705-derived soybean plants; and © repeating the crossing and growing steps of (a) and (b) to generate further soybean variety A1023705-derived soybean plants. In specific embodiments, steps (a) and (b) may be repeated at least 1, 2, 3, 4, or 5 or more times as desired. The invention still further provides a soybean plant produced by this and the foregoing methods."
