Cotton variety 05Y070

A method of introducing a single locus conversion into cotton variety 05Y070 comprising:

• (a) crossing a plant of variety 05Y070 with a second plant to produce cotton seed, wherein the second plant comprises a desired single locus, wherein a sample of seed of said variety has been deposited under ATCC Accession No. PTA-11558;
• (b) growing F1 progeny plants from the seed and selecting at least a first F1 progeny plant that has the single locus to produce selected F1 progeny plants;
• (c) crossing the selected progeny plants with at least a first plant of variety 05Y070 to produce backcross progeny plants;
• (d) selecting backcross progeny plants that have the single locus and physiological and morphological characteristics of cotton variety 05Y070 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 05Y070 when grown in the same environmental conditions.

A method of producing an inbred cotton plant derived from the cotton variety 05Y070, the method comprising the steps of:

• (a) obtaining cotton seed by crossing a plant of cotton variety 05Y070 with a second, distinct cotton plant, and growing at least a first seed to produce a progeny plant, wherein a sample of seed of said variety has been deposited under ATCC Accession No. PTA-11558;
• (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 05Y070.
