10. A seed of hybrid corn variety CH102421 comprising at least a first single locus conversion, produced by crossing a first plant of variety CV045443 with a second plant of variety CV651587, wherein representative seed of said varieties CV045443 and CV651587 have been deposited under ATCC Accession numbers PTA-123037 and PTA-120301, 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 CH102421.

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 CH102421 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 CV045443 and variety CV651587 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 CV045443 and variety CV651587 have been deposited under ATCC Accession numbers PTA-123037 and PTA-120301, 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 CV045443 and CV651587 to produce a plant of hybrid corn variety CH102421 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 CH102421, 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 of hybrid corn variety CH102421 produced by the method of claim 13 , wherein said plant comprises the heritable trait and otherwise comprises essentially all of the morphological and physiological characteristics of hybrid corn variety CH102421.

17. A method of producing a corn plant derived from the hybrid corn variety CH102421, 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 CH102421.

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

(a) crossing the progeny corn plant derived from the hybrid corn variety CH102421 with itself or a second plant to produce a seed of a progeny plant of a subsequent generation;
