Cotton variety 05Y063

A method of introducing a single locus conversion into cotton variety 05Y063 comprising:

• (a) crossing a plant of variety 05Y063, a representative sample of seed of said variety having been deposited under ATCC Accession No. PTA-9899, with a second plant comprising a desired single locus to produce F1 progeny plants;
• (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 05Y063 to produce backcross progeny plants;
• (d) selecting backcross progeny plants that have the single locus and physiological and morphological characteristics of cotton variety 05Y063 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 cotton variety 05Y063 when grown in the same environmental conditions.

A method of producing an inbred cotton plant derived from the cotton variety 05Y063, the method comprising the steps of:

• (a) preparing a progeny plant derived from cotton variety 05Y063, a representative sample of seed of said variety having been deposited under ATCC Accession No. PTA-9899, by crossing cotton variety 05Y063 with a cotton 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 cotton plant derived from the cotton variety 05Y063.
