Abstract

According to the invention, there is provided seed and plants of the hybrid corn variety designated CH781092. The invention thus relates to the plants, seeds and tissue cultures of the variety CH781092, and to methods for producing a corn plant produced by crossing a corn plant of variety CH781092 with itself or with another corn plant, such as a plant of another variety. The invention further relates to genetic complements of plants of variety CH781092.

Claims

1. A seed of the hybrid corn variety CH781092, produced by crossing a first plant of variety I180580 with a second plant of variety CV704139, wherein representative seed of said varieties I180580 and CV704139 have been deposited under ATCC Accession numbers PTA-4490 and PTA-11129, respectively.

2. A plant of the hybrid corn variety CH781092 grown from the seed of claim 1.

3. A plant part of the plant of claim 2.

4. The plant part of claim 3, further defined as an ear, ovule, pollen or cell.

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

6. The tissue culture of claim 5, wherein cells of the tissue culture are from a tissue selected from the group consisting of leaf, pollen, embryo, root, root tip, anther, silk, flower, kernel, ear, cob, husk, stalk and meristem.

7. The seed of claim 1, further comprising a transgene.

8. The seed of claim 7, wherein the transgene confers a trait selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, waxy starch, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.

9. The plant of claim 2, further comprising a transgene.

23. A method of producing a corn plant derived from the hybrid corn variety CH781092, comprising crossing the plant of claim 2 with a second corn plant to produce a progeny corn plant derived from the hybrid corn variety CH781092.

24. The method of claim 23, further comprising the steps of:

(a) crossing the progeny corn plant derived from the hybrid corn variety CH781092 with itself or a second plant to produce a seed of a progeny plant of a subsequent generation;

(b) growing a progeny plant of a subsequent generation from the seed and crossing the progeny plant of a subsequent generation with itself or a second plant; and

(c) repeating steps (a) and (b) for an additional 3-10 generations to produce a corn plant further derived from the hybrid corn variety CH781092.

25. The method of claim 24, further comprising the step of:

(d) crossing the corn plant further derived from the hybrid corn variety CH781092 with a second, distinct corn plant.

26. A method of producing a commodity plant product comprising obtaining the plant of claim 2 or a part thereof and producing said commodity plant product therefrom.

27. The method of claim 26, wherein the commodity plant product is grain, starch, seed oil, corn syrup or protein.

10. A method of producing hybrid corn seed comprising crossing a plant of variety I180580 with a plant of variety CV704139, wherein representative seed of variety I180580 and variety CV704139 have been deposited under ATCC Accession numbers PTA-4490 and PTA-11129, respectively.

11. The method of claim 10, wherein the plant of inbred variety I180580 is pollinated with pollen from a plant of variety CV704139.

12. The method of claim 10, wherein the plant of inbred variety CV704139 is pollinated with pollen from a plant of variety I180580.

13. A method of introducing a heritable trait into hybrid corn variety CH781092 comprising the steps of:

(a) introducing at least a first heritable trait into at least one inbred corn variety selected from the group consisting of variety I180580 and variety CV704139 to produce a plant of the first inbred corn variety that heritably carries the trait, wherein the heritable trait is introduced into said first inbred corn variety by backcrossing and wherein representative samples of seed of variety I180580 and variety CV704139 have been deposited under ATCC Accession numbers PTA-4490 and PTA-11129, respectively; and

(b) crossing a plant of the first inbred corn variety that heritably carries the trait with a plant of a different variety selected from said group consisting of I180580 and CV704139 to produce a plant of hybrid corn variety CH781092 comprising the heritable trait.

14. The method of claim 13, wherein the trait is selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, waxy starch, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.

15. The method of claim 14, further comprising repeating step (a) at least once to introduce at least a second heritable trait into hybrid corn variety CH781092, wherein the second heritable trait is selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, waxy starch, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.

16. A plant produced by the method of claim 13.

17. A seed that produces the plant of claim 16.

18. A method of introducing a trait into hybrid corn variety CH781092 comprising the steps of:

(a) introducing a transgene conferring the trait into a variety selected from the group consisting of I180580 and CV704139 to produce a transgenic plant heritably carrying the trait, wherein representative samples of seed of variety I180580 and variety CV704139 have been deposited under ATCC Accession numbers PTA-4490 and PTA-11129, respectively; and

(b) crossing the transgenic plant or an isogenic progeny plant thereof with a plant of a different variety selected from the group consisting of I180580 and CV704139 to produce a plant of the hybrid corn variety CH781092 that comprises the trait.

19. The method of claim 18, wherein the desired trait is selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, waxy starch, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.

20. The method of claim 18, further comprising repeating step (a) at least once to introduce at least a second trait into hybrid corn variety CH781092, wherein the second trait is selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, waxy starch, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.

21. A plant produced by the method of claim 18.

22. The plant of claim 21, wherein the plant comprises a trait selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, waxy starch, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.
