Abstract

According to the invention, there is provided seed and plants of the hybrid corn variety designated CH445169. The invention thus relates to the plants, seeds and tissue cultures of the variety CH445169, and to methods for producing a corn plant produced by crossing a corn plant of variety CH445169 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 CH445169.

First claim

What is claimed is:

1. A seed of the hybrid corn variety CH445169, produced by crossing a first plant of variety CV995128 with a second plant of variety CV197629, wherein representative seed of said varieties CV995128 and CV197629 have been deposited under ATCC Accession numbers PTA-11307 and PTA-120299, respectively.

2. A plant of the hybrid corn variety CH445169 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.

9. A method of producing the seed of claim 1 comprising crossing a plant of variety CV995128 with a plant of variety CV197629, wherein representative seed of variety CV995128 and variety CV197629 have been deposited under ATCC Accession numbers PTA-11307 and PTA-120299, respectively.

10. A seed of the hybrid corn variety CH445169 further comprising at least a first single locus conversion, produced by crossing a first plant of variety CV995128 with a second plant of variety CV197629, wherein representative seed of said varieties CV995128 and CV197629 have been deposited under ATCC Accession numbers PTA-11307 and PTA-120299, respectively, and wherein one or both of the first plant and second plant comprises the single locus conversion, and wherein a plant grown from said seed comprises a trait conferred by said at least a first single locus conversion and otherwise comprises essentially all of the morphological and physiological characteristics of hybrid corn variety CH445169.

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 a hybrid corn variety 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 CV995128 and variety CV197629 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 CV995128 and variety CV197629 have been deposited under ATCC Accession numbers PTA-11307 and PTA-120299, 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 CV995128 and CV197629 to produce a plant of hybrid corn variety CH445169 comprising the heritable trait and essentially all the morphological and physiological characteristics of hybrid corn variety CH445169.

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 13 , wherein step (a) further comprises introducing at least a second heritable trait into said at least one inbred corn variety, 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 , wherein the hybrid plant comprises the heritable trait and otherwise comprises essentially all of the morphological and physiological characteristics of corn variety CH445169.

17. A method of producing a corn plant derived from the hybrid corn variety CH445169, 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 CH445169.

18. The method of claim 17 , further comprising the steps of:
(a) crossing the progeny corn plant derived from the hybrid corn variety CH445169 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 CH445169.

19. The method of claim 18 , further comprising the step of:
(d) crossing the corn plant further derived from the hybrid corn variety CH445169 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.
