Plants and seeds of hybrid corn variety CH406206

A method of producing hybrid corn seed comprising crossing a plant of variety CV774864 with a plant of variety CV678689, wherein representative seed of variety CV774864 and variety CV678689 have been deposited under ATCC Accession numbers PTA-11317 and PTA-120297, respectively.

A seed of hybrid corn variety CH406206 further comprising at least one single locus conversion, produced by crossing a first plant of variety CV774864 with a second plant of variety CV678689, wherein representative seed of said varieties CV774864 and CV678689 have been deposited under ATCC Accession numbers PTA-11317 and PTA-120297, 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 CH406206 listed in Table 1 when grown under the same environmental conditions.

A method of introducing a heritable trait into hybrid corn variety CH406206 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 CV774864 and variety CV678689 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 CV774864 and variety CV678689 have been deposited under ATCC Accession numbers PTA-11317 and PTA-120297, 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 CV774864 and CV678689 to produce a plant of hybrid corn variety CH406206 comprising the heritable trait.
