Plants and seeds of hybrid corn variety CH286440

A method of producing hybrid corn seed comprising crossing a plant of variety CV847814 with a plant of variety CV597869, wherein representative seed of variety CV847814 and variety CV597869 have been deposited under ATCC Accession numbers PTA-120298 and PTA-10885, respectively.

A seed of hybrid corn variety CH286440 further comprising at least one single locus conversion, produced by crossing a first plant of variety CV847814 with a second plant of variety CV597869, wherein representative seed of said varieties CV847814 and CV597869 have been deposited under ATCC Accession numbers PTA-120298 and PTA-10885, respectively, and wherein one or both of the first plant and second plant further comprises the single locus conversion, and wherein a hybrid plant grown from the seed comprises the single locus conversion and otherwise essentially all of the morphological and physiological characteristics of hybrid corn variety CH286440 listed in Table 1 when grown under the same environmental conditions.

A method of introducing a heritable trait into hybrid corn variety CH286440 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 CV847814 and variety CV597869 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 CV847814 and variety CV597869 have been deposited under ATCC Accession numbers PTA-120298 and PTA-10885, 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 CV847814 and CV597869 to produce a plant of hybrid corn variety CH286440 comprising the heritable trait.
