Abstract

According to the invention, there is provided seed and plants of the hybrid corn variety designated CH199546. The invention thus relates to the plants, seeds and tissue cultures of the variety CH199546 , and to methods for producing a corn plant produced by crossing a corn plant of variety CH199546 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 CH199546.

Claims

1. A seed of the hybrid corn variety CH199546, produced by crossing a first plant of variety CV374246 with a second plant of variety I285291, wherein representative seed of said varieties CV374246 and I285291 have been deposited under ATCC Accession numbers PTA-10672 and PTA-7994, respectively.

2. A plant of the hybrid corn variety CH199546 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 composition comprising the seed of claim 1 comprised in plant seed growth media.

6. The composition of claim 5, wherein the growth media is soil or a synthetic cultivation medium.

7. The seed of claim 1, further comprising at least a first 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.

17. A method of producing a corn plant derived from the hybrid corn variety CH199546, wherein the method comprises crossing the plant of claim 2 with a second corn plant to produce a progeny corn plant derived from the hybrid corn variety CH199546.

18. The method of claim 17, further comprising the steps of:

(a) crossing the progeny corn plant derived from the hybrid corn variety CH199546 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 at least an additional 3-10 generations to produce a corn plant further derived from the hybrid corn variety CH199546.

19. The method of claim 18, further comprising the step of:

(d) crossing the corn plant further derived from the hybrid corn variety CH199546 with a second, distinct corn plant.

20. 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.

21. The method of claim 20, wherein the commodity plant product is grain, starch, seed oil, corn syrup or protein.

9. A method of producing hybrid corn seed comprising crossing a plant of variety CV374246 with a plant of variety I285291, wherein representative seed of variety CV374246 and variety I285291 have been deposited under ATCC Accession numbers PTA-10672 and PTA-7994, respectively.

10. A seed of the hybrid corn variety CH199546 comprising at least a first single locus conversion, produced by crossing a first plant of variety CV374246 with a second plant of variety I285291, wherein representative seed of said varieties CV374246 and I285291 have been deposited under ATCC Accession numbers PTA-10672 and PTA-7994, respectively, and wherein one or both of the first plant and second plant comprises the single locus conversion.

11. The seed of claim 10, wherein the single locus conversion 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.

12. A plant grown from the seed of claim 10.

13. A method of introducing a heritable trait into hybrid corn variety CH 199546 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 CV374246 and variety I285291 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 CV374246 and variety I285291 have been deposited under ATCC Accession numbers PTA-10672 and PTA-7994, 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 CV374246 and I285291 to produce a plant of hybrid corn variety CH199546 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 CH199546, 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.
