Abstract

A soybean cultivar designated 306924721 is disclosed. The invention relates to the seeds of soybean cultivar 306924721, to the plants of soybean 306924721, to plant parts of soybean cultivar 306924721 and to methods for producing a soybean plant produced by crossing soybean cultivar 306924721 with itself or with another soybean variety. The invention also relates to methods for producing a soybean plant containing in its genetic material one or more transgenes and to the transgenic soybean plants and plant parts produced by those methods. This invention also relates to soybean cultivars or breeding cultivars and plant parts derived from soybean variety 306924721, to methods for producing other soybean cultivars, lines or plant parts derived from soybean cultivar 306924721 and to the soybean plants, varieties, and their parts derived from use of those methods. The invention further relates to hybrid soybean seeds, plants and plant parts produced by crossing the cultivar 306924721 with another soybean cultivar.

Claims

1. A seed of soybean cultivar 306924721, representative sample seed of said cultivar was deposited under ATCC Accession No. PTA-10368.

2. A soybean plant, or a part thereof, produced by growing the seed of claim 1.

3. A tissue culture produced from protoplasts or cells from the plant of claim 2, wherein said cells or protoplasts of the tissue culture are produced from a plant part selected from the group consisting of leaf, pollen, embryo, cotyledon, hypocotyl, meristematic cell, root, root tip, pistil, anther, flower, shoot, stem, pod and petiole.

4. A soybean plant regenerated from the tissue culture of claim 3, wherein the plant has all of the morphological and physiological characteristics of cultivar 306924721.

5. A method for producing a soybean seed comprising crossing two soybean plants and harvesting the resultant soybean seed, wherein at least one soybean plant is the soybean plant of claim 2.

6. A soybean seed produced by the method of claim 5.

7. A soybean plant, or a part thereof, produced by growing said seed of claim 6.

8. A method of producing an herbicide resistant soybean plant wherein the method comprises transforming the soybean plant of claim 2 with a transgene wherein the transgene confers resistance to an herbicide selected from the group consisting of imidazolinone, cyclohexanedione, sulfonylurea, glyphosate, glufosinate, phenoxy proprionic acid, L-phosphinothricin, triazine and benzonitrile.

9. An herbicide resistant soybean plant produced by the method of claim 8.

10. A method of producing a pest or insect resistant soybean plant wherein the method comprises transforming the soybean plant of claim 2 with a transgene that confers pest or insect resistance.

11. A pest or insect resistant soybean plant produced by the method of claim 10.

12. The soybean plant of claim 11, wherein the transgene encodes a Bacillus thuringiensis endotoxin.

13. A method of producing a disease resistant soybean plant wherein the method comprises transforming the soybean plant of claim 2 with a transgene that confers disease resistance.

14. A disease resistant soybean plant produced by the method of claim 13.

15. 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 phytase, fructosyltransferase, levansucrase, α

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

16. A soybean plant having modified fatty acid metabolism or modified carbohydrate metabolism produced by the method of claim 15.

17. A method of introducing a desired trait into soybean cultivar 306924721 wherein the method comprises:

(a) crossing a 306924721 plant, wherein a representative sample of seed was deposited under ATCC Accession No. PTA-10368, with a plant of another soybean cultivar that comprises a desired trait to produce progeny plants wherein the desired trait is selected from the group consisting of male sterility, herbicide resistance, insect resistance, modified fatty acid metabolism, modified carbohydrate metabolism, modified seed yield, modified oil percent, modified protein percent, modified lodging resistance, modified shattering, modified iron-deficiency chlorosis and resistance to bacterial disease, fungal disease 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 the 306924721 plants to produce backcross progeny plants;

(d) selecting for backcross progeny plants that have the desired trait and all of the physiological and morphological characteristics of soybean cultivar 306924721 listed in Table 1; 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 306924721 listed in Table 1.

18. A soybean plant produced by the method of claim 17, wherein the plant has the desired trait.

19. The soybean plant of claim 18, wherein the desired trait is herbicide resistance and the resistance is conferred to an herbicide selected from the group consisting of imidazolinone, cyclohexanedione, sulfonylurea, glyphosate, glufosinate, phenoxy proprionic acid, L-phosphinothricin, triazine and benzonitrile.

20. The soybean plant of claim 18, wherein the desired trait is insect resistance and the insect resistance is conferred by a transgene encoding a Bacillus thuringiensis endotoxin.

21. The soybean plant of claim 18, 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 phytase, fructosyltransferase, levansucrase, α

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