Plants and seeds of corn variety CV390455

A method of introducing a single locus conversion into corn variety CV390455 comprising:

• (a) crossing a plant of variety CV390455 with a second plant comprising a desired single locus to produce F1 progeny plants, wherein a sample of seed of corn variety CV390455 has been deposited under ATCC Accession No. PTA-10035;
• (b) selecting F1 progeny plants that have the single locus to produce selected F1 progeny plants;
• (c) crossing the selected progeny plants with at least a first plant of variety CV390455 to produce backcross progeny plants;
• (d) selecting backcross progeny plants that have the single locus and physiological and morphological characteristics of corn variety CV390455 to produce selected backcross progeny plants;
• and
• (e) repeating steps (c) and (d) one or more times in succession to produce selected second or higher backcross progeny plants that comprise the single locus and otherwise comprise all of the physiological and morphological characteristics of corn variety CV390455 when grown in the same environmental conditions.

A method of producing an inbred corn plant derived from the corn variety CV390455, wherein a sample of seed of corn variety CV390455 has been deposited under ATCC Accession No. PTA-10035, the method comprising the steps of:

• (a) preparing a progeny plant derived from corn variety CV390455 by crossing a plant of the corn variety CV390455 with a corn plant of a second variety;
• (b) crossing the progeny plant with itself or a second plant to produce a seed of a progeny plant of a subsequent generation;
• (c) growing a progeny plant of a subsequent generation from said seed and crossing the progeny plant of a subsequent generation with itself or a second plant;
• and
• (d) repeating steps (b) and (c) for an additional 3-10 generations with sufficient inbreeding to produce an inbred corn plant derived from the corn variety CV390455.
