Abstract
The invention provides seed and plants of the hybrid corn variety designated 22250190. The invention thus relates to the plants, seeds and tissue cultures of the variety 22250190, and to methods for producing a corn plant produced by crossing a corn plant of variety 22250190 with itself or with another corn plant, such as a plant of another variety. The invention further relates to genetic complements of plants of variety 22250190.
Claims20
A seed of the hybrid corn variety 22250190, produced by crossing a first plant of variety MN7224 with a second plant of variety DES08, wherein representative seed of said varieties MN7224 and DES08 have been deposited under ATCC Accession numbers PTA-5451 and PTA-123460, respectively.
A method of producing hybrid corn seed comprising crossing a plant of variety MN7224 with a plant of variety DES08, wherein representative seed of variety MN7224 and variety DES08 have been deposited under ATCC Accession numbers PTA-5451 and PTA-123460, respectively.
A method of introducing a heritable trait into hybrid corn variety 22250190 comprising the steps of:
- (a) crossing a first plant of a first inbred corn variety selected from the group consisting of variety MN7224 and variety DES08 with another corn plant that heritably carries the trait to produce progeny plants, at least some of which heritably carry the trait, wherein representative samples of seed of variety MN7224 and variety DES08 have been deposited under ATCC Accession numbers PTA-5451 and PTA-123460, respectively;
- (b) selecting progeny plants that heritably carry the trait;
- (c) crossing selected progeny plants with another plant of the first inbred corn variety to produce next-generation progeny plants at least some of which heritably carry the trait;
- (d) selecting next-generation progeny plants that heritably carry the trait and exhibit morphological and physiological characteristics of the first inbred corn variety;
- (e) repeating steps (c) and (d) three or more times to produce at least a first selected progeny plant that heritably carries the trait and otherwise exhibits the morphological and physical characteristics of the first inbred corn variety;
- and
- (f) crossing the selected progeny plant of step (e) with a plant of the other inbred corn variety of the group consisting of MN7224 and DES08 to produce a plant comprising the trait and otherwise comprising all of the morphological and physiological characteristics of hybrid corn variety 22250190 when grown under the same environmental conditions.
A method of introducing a desired trait into hybrid corn variety 22250190 comprising the steps of:
- (a) introducing a transgene conferring the trait into a variety selected from the group consisting of MN7224 and DES08 to produce a transgenic plant heritably carrying the trait;
- and
- (b) crossing the transgenic plant or an isogenic progeny plant thereof with a plant of the other inbred corn variety to produce seed of the hybrid corn variety 22250190 that heritably carries and expresses the transgene and otherwise has all of the morphological and physiological characteristics of hybrid corn variety 22250190 when grown under the same environmental conditions.
