Abstract

According to the invention, there is provided seed and plants of the hybrid corn variety designated CH408813. The invention thus relates to the plants, seeds and tissue cultures of the variety CH408813, and to methods for producing a corn plant produced by crossing a corn plant of variety CH408813 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 CH408813.

Claims

1. A seed of the hybrid corn variety CH408813, produced by crossing a first plant of variety I180580 with a second plant of variety CV548123, wherein representative seed of said varieties I180580 and CV548123 have been deposited under ATCC Accession numbers PTA-4490 and PTA-______, respectively.

2. A plant of the hybrid corn variety CH408813 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, wherein one or both of the first and second plants further comprises 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 seed of claim 7, wherein the first and second plants each comprise a different transgene.

10. The seed of claim 7, wherein one or both of the first and second plants comprises a 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.

15. A method for producing corn grain comprising growing the plant of claim 2 until grain is produced and collecting the grain.

25. A method of producing a corn plant derived from the hybrid corn variety CH408813, comprising crossing the plant of claim 2 with a second corn plant to produce a progeny corn plant derived from the hybrid corn variety CH408813.

26. The method of claim 25, further defined as comprising producing an inbred corn plant derived from the hybrid corn variety CH408813, the method comprising the steps of:

(a) crossing the progeny corn plant derived from the hybrid corn variety CH408813 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 with sufficient inbreeding to produce an inbred corn plant derived from the hybrid corn variety CH408813.

12. A method of producing hybrid corn seed comprising crossing a plant of variety 1180580 with a plant of variety CV548123, wherein representative seed of variety 1180580 and variety CV548123 have been deposited under ATCC Accession numbers PTA-4490 and PTA-______, respectively.

13. The method of claim 12, defined as comprising pollinating a plant of inbred variety I180580 with pollen from a plant of variety CV548123.

14. The method of claim 12, defined as comprising pollinating a plant of inbred variety CV548123 with pollen from a plant of variety I180580.

16. A method of introducing a heritable trait into hybrid corn variety CH408813 comprising the steps of:

(a) crossing a first plant of a first inbred corn variety selected from the group consisting of variety I180580 and variety CV548123 with another corn plant that heritably carries the trait to produce progeny plants, at least some of which heritably carry the trait, wherein representative samples of seed of variety I180580 and variety CV548123 have been deposited under ATCC Accession numbers PTA-4490 and PTA-______, respectively;

(b) selecting progeny plants that heritably carry the trait;

(c) crossing selected progeny plants with another plant of the first inbred corn variety to produce next-generation progeny plants at least some of which heritably carry the trait;

(d) selecting next-generation progeny plants that heritably carry the trait and exhibit morphological and physiological characteristics of the first inbred corn variety;

(e) repeating steps (c) and (d) three or more times to produce at least a first selected progeny plant that heritably carries the trait and exhibits essentially all of the morphological and physical characteristics of the inbred corn variety; and

(f) crossing a progeny plant of step (e) with a plant of the other inbred corn variety of the group consisting of I180580 and CV548123 to produce a plant comprising the trait and essentially all of the characteristics of hybrid corn variety CH408813 when grown under the same environmental conditions.

17. The method of claim 16, 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.

18. The method of claim 17, further comprising repeating steps (a)-(f) at least once to introduce at least a second trait into hybrid corn variety CH408813, 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.

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

20. A method of introducing a desired trait into hybrid corn variety CH408813 comprising the steps of:

(a) introducing a transgene conferring the trait into a variety selected from the group consisting of I180580 and CV548123 to produce a transgenic plant heritably carrying the trait; and

(b) crossing the transgenic plant or an isogenic progeny plant thereof with a plant of the other inbred corn variety to produce seed of the hybrid corn variety CH408813 that heritably carries and expresses the transgene and otherwise has essentially all of the morphological and physiological characteristics of hybrid corn variety CH408813 when grown under the same environmental conditions.

21. The method of claim 20, wherein the desired 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.
