Plants and seeds of hybrid corn variety CH175075

A method of producing hybrid corn seed comprising crossing a plant of variety I226211 with a plant of variety CV397654, wherein representative seed of variety I226211 and variety CV397654 have been deposited under ATCC Accession numbers PTA-8214 and PTA-13538, respectively.

A seed of hybrid corn variety CH175075 further comprising at least one single locus conversion, produced by crossing a first plant of variety I226211with a second plant of variety CV397654, wherein representative seed of said varieties I226211and CV397654 have been deposited under ATCC Accession numbers PTA-8214 and PTA-13538, 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 CH175075 listed in Table 1 when grown under the same environmental conditions.

A method of introducing a heritable trait into hybrid corn variety CH175075 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 I226211 and variety CV397654 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 I226211 and variety CV397654 have been deposited under ATCC Accession numbers PTA-8214and PTA-13538, 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 I226211 and CV397654 to produce a plant of hybrid corn variety CH175075 comprising the heritable trait.
