Plants and seeds of hybrid corn variety CH010557

A seed of hybrid corn variety CH010557 further comprising a single locus conversion, wherein a plant grown from said seed comprises a trait conferred by said single locus conversion and otherwise comprises all of the morphological and physiological characteristics of hybrid corn variety CH010557 when grown under the same environmental conditions, and wherein said seed is produced by crossing a first plant selected from the group consisting of variety CV761500 and selfed progeny thereof with a second plant selected from a second group consisting of variety CV558666 and selfed progeny thereof, wherein said first plant, said second plant, or both further comprise said single locus conversion, and wherein representative seeds of said varieties CV761500 and CV558666 are deposited under NCMA Accession No. 202005026 and NCMA Accession No. 202206031, respectively.

A method of introducing a heritable trait into hybrid corn variety CH010557, the method comprising the steps of:

• (a) introducing at least said heritable trait into a first inbred corn variety CV761500, a second inbred corn variety CV558666, or both inbred corn varieties CV761500 and CV558666 to produce plants of said inbred corn varieties that heritably carry said heritable trait, wherein said heritable trait is introduced into said inbred corn varieties by backcrossing, wherein said backcrossing is sufficient to produce an inbred corn variety further comprising said heritable trait, and wherein representative seeds of said inbred corn varieties CV761500 and CV558666 are deposited under NCMA Accession No. 202005026 and NCMA Accession No. 202206031, respectively;
• and
• (b) producing a plant of hybrid corn variety CH010557 further comprising said heritable trait by crossing a plant of said first or said second inbred corn variety that heritably carries said heritable trait with a plant of a different inbred corn variety selected from a group consisting of inbred corn varieties CV761500 and CV558666, or crossing a plant of said first inbred corn variety and a plant of said second inbred corn variety that both heritably carry said heritable trait.
