7. The seed of claim 6 , 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.
8. A method of producing the seed of claim 1 , the method comprising crossing a hybrid plant having varieties CV483519 and CV995128 as parents with a plant of variety CV644326.
9. A seed of hybrid corn variety CH954609 further comprising a single locus conversion, wherein a plant grown from said seed comprises a trait conferred by said single locus conversion and otherwise comprises all of the morphological and physiological characteristics of hybrid corn variety CH954609, and wherein said seed is produced by crossing a hybrid plant having inbred varieties CV483519 and CV995128 as parents with a plant selected from the group consisting of variety CV644326 and selfed progeny thereof, wherein said hybrid plant, said plant, or both further comprise said single locus conversion, and wherein representative seeds of said varieties CV483519, CV995128, and CV644326, are deposited under ATCC Accession Nos. PTA-12082, PTA-11307, and PTA-125218, respectively.
10. The seed of claim 9 , wherein said 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.
11. A plant grown from the seed of claim 9 , wherein said plant comprises said trait and otherwise comprises all of the morphological and physiological characteristics of hybrid corn variety CH954609.
12. A method of introducing a heritable trait into hybrid corn variety CH954609, the method comprising the steps of:
(a) introducing at least said heritable trait into one or more of inbred corn varieties CV483519, CV995128, and CV644326 to produce plants of said inbred corn varieties that heritably carry said heritable trait, wherein said heritable trait is introduced into said inbred corn varieties by backcrossing, wherein said backcrossing is sufficient to produce an inbred corn variety further comprising said heritable trait, and wherein representative seeds of said inbred corn varieties CV483519, CV995128, and CV644326, are deposited under ATCC Accession Nos. PTA-12082, PTA-11307, and PTA-125218, respectively; and
(b) performing a cross, wherein a plant of inbred corn variety CV483519 is crossed with a plant of inbred corn variety CV995128 to produce a first hybrid plant and the first hybrid plant is crossed with a plant of inbred corn variety CV644326 to produce a plant of said hybrid corn variety CH954609 further comprising said heritable trait, and wherein one or more of said inbred plants used in said cross were produced by step (a) and heritably carry said heritable trait.
13. The method of claim 12 wherein said 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.
14. The method of claim 12 further comprising repeating step (a) at least once to introduce at least a second heritable trait into hybrid corn variety CH954609, 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.
15. A plant produced by the method of claim 12 , wherein said plant comprises said heritable trait and otherwise comprises all of the morphological and physiological characteristics of corn variety CH954609 when grown under the same environmental conditions.
16. A method of producing a progeny corn plant derived from hybrid corn variety CH954609, wherein the method comprises applying plant breeding techniques to the plant of claim 2 to produce said progeny corn plant derived from hybrid corn variety CH954609.
17. The method of claim 16 , wherein said plant breeding techniques comprise backcrossing, marker assisted breeding, pedigree breeding, selfing, outcrossing, haploid production, doubled haploid production, or transformation.
18. The method of claim 16 , further comprising the steps of:
(a) crossing said progeny corn plant derived from hybrid corn variety CH954609 with itself or a second plant to produce a seed of a progeny plant of a subsequent generation;
(b) growing the progeny plant of the subsequent generation from said seed of the progeny plant of the subsequent generation; and
(c) repeating steps (a) and (b) for at least an additional 3-10 generations to produce a progeny corn plant further derived from the hybrid corn variety CH954609.
19. A method of producing a commodity plant product, the method comprising obtaining the plant of claim 2 or a plant part thereof and producing said commodity plant product therefrom, wherein said plant part comprises a cell of hybrid corn variety CH954609.
