Abstract

A novel soybean cultivar, designated SG1120RR, is disclosed. The invention relates to the seeds of soybean cultivar SG1120RR, to the plants of soybean SG1120RR and to methods for producing a soybean plant produced by crossing the cultivar SG1120RR with itself or another soybean variety. The invention further relates to hybrid soybean seeds and plants produced by crossing the cultivar SG1120RR with another soybean cultivar.

Claims

1. A seed of a soybean cultivar designated SG1120RR wherein a representative sample of seed was deposited under ATCC Accession No. PTA-7320.

2. A soybean plant, or a part thereof, of soybean cultivar SG1120RR, wherein a representative sample of seed of said cultivar was deposited under ATCC Accession No. PTA-7320.

3. Pollen of the plant of claim 2.

4. An ovule of the plant of claim 2.

5. A tissue culture of cells produced from the plant of claim 2.

6. The tissue culture according to claim 5, wherein said cells of the tissue culture are produced from a plant part selected from the group consisting of leaves, pollen, embryos, cotyledons, hypocotyl, meristematic cells, roots, root tips, anthers, flowers, pistils, seeds, stems and pods.

7. A soybean plant regenerated from the tissue culture of claim 5, wherein the regenerated plant has all of the morphological and physiological characteristics of soybean cultivar SG1120RR and wherein a representative sample of seed was deposited under ATCC Accession No. PTA-7320.

8. A method for producing a hybrid soybean seed comprising crossing a first parent soybean plant with a second parent soybean plant and harvesting the resultant hybrid soybean seed, wherein said first parent soybean plant or said second parent soybean plant is the soybean plant of claim 2.

9. A method for producing a soybean plant that contains in its genetic material a transgene, comprising crossing the soybean plant of claim 2 with either a second plant of another soybean cultivar which contains a transgene or a transformed soybean plant of soybean cultivar SG1120RR, so that the genetic material of the progeny that result from the cross contains a transgene operably linked to a regulatory element wherein said transgene confers a trait selected from the group consisting of herbicide resistance, insect resistance, and disease resistance.

10. A method of producing a soybean plant with modified fatty acid metabolism or modified carbohydrate metabolism wherein the method comprises transforming the soybean plant of claim 2 with a transgene encoding a protein selected from the group consisting of fructosyltransferase, levansucrase, a-amylase, invertase, and starch branching enzyme or encoding an antisense of stearyl-ACP desaturase.

11. A soybean plant having modified fatty acid metabolism or modified carbohydrate metabolism produced by the method of claim 10.

17. A method of producing a male sterile soybean plant wherein the method comprises transforming the soybean plant of claim 2 with a nucleic acid molecule that confers male sterility.

18. A male sterile soybean plant produced by the method of claim 17.

19. A protoplast produced from the plant of claim 2.

20. A protoplast produced from the tissue culture of claim 5.

21. A soybean plant regenerated from the protoplast of claim 19, wherein the regenerated plant has all of the morphological and physiological characteristics of soybean cultivar SG1120RR as described in the VARIETY DESCRIPTION INFORMATION and wherein a representative sample of seed was deposited under ATCC Accession No. PTA-7320.

22. A soybean plant regenerated from the protoplast of claim 20, wherein the regenerated plant has all of the morphological and physiological characteristics of soybean cultivar SG1120RR as described in the VARIETY DESCRIPTION INFORMATION and wherein a representative sample of seed was deposited under ATCC Accession No. PTA-7320.

12. A method of introducing a desired trait into soybean cultivar SG1120RR wherein the method comprises:

(a) crossing SG1120RR plants, grown from seed deposited under ATCC Accession No. PTA-7320, with plants of another soybean cultivar that comprise a desired trait to produce progeny plants, wherein the desired trait is selected from the group consisting of herbicide resistance, insect resistance, modified fatty acid metabolism, modified carbohydrate metabolism, and resistance to bacterial, fungal or viral disease;

(b) selecting one or more progeny plants that have the desired trait to produce selected progeny plants;

(c) crossing the selected progeny plants with SG1120RR plants to produce backcross progeny plants;

(d) selecting for backcross progeny plants that have the desired trait and physiological and morphological characteristics of soybean cultivar SG1120RR to produce selected backcross progeny plants; and

(e) repeating steps (c) and (d) three or more times in succession to produce selected fourth or higher backcross progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of soybean cultivar SG1120RR as described in the VARIETY DESCRIPTION INFORMATION.

13. A soybean plant produced by the method of claim 12, wherein the plant has the desired trait and all of the physiological and morphological characteristics of soybean cultivar SG1120RR as described in the VARIETY DESCRIPTION INFORMATION.

14. The soybean plant of claim 13, wherein the desired trait is herbicide resistance and the resistance is conferred to an herbicide selected from the group consisting of imidazolinone, sulfonylurea, glyphosate, glufosinate, L-phosphinothricin, triazine, and benzonitrile.

15. The soybean plant of claim 13, wherein the desired trait is insect resistance and the insect resistance is conferred by a transgene encoding a Bacillus thuringiensis endotoxin.

16. The soybean plant of claim 13, wherein the desired trait is modified fatty acid metabolism or modified carbohydrate metabolism and said desired trait is conferred by a nucleic acid encoding a protein selected from the group consisting of fructosyltransferase, levansucrase, α

-amylase, invertase, and starch branching enzyme or encoding an antisense of stearyl-ACP desaturase.
