Abstract
A novel cotton cultivar, designated DP 494 RR, is disclosed. The invention relates to the seeds of cotton cultivar DP 494 RR, to the plants of cotton DP 494 RR and to methods for producing a cotton plant produced by crossing the cultivar DP 494 RR with itself or another cotton variety. The invention further relates to hybrid cotton seeds and plants produced by crossing the cultivar DP 494 RR with another cotton cultivar.
Claims27
Seed of cotton line designated DP 494 RR, representative seed of said line having been deposited under ATCC Accession No. PTA-______.
A cotton plant, or part thereof, having all the physiological and morphological characteristics of the line DP 494 RR, representative seed of said line having been deposited under ATCC Accession No. PTA-______.
A method of introducing a desired trait into cotton line DP 494 RR comprising:
- (a) crossing DP 494 RR plants grown from DP 494 RR seed, representative seed of which has been deposited under ATCC Accession No. PTA-______, with plants of another cotton line that comprise a desired trait to produce F1 progeny plants, wherein the desired trait is selected from the group consisting of male sterility, herbicide resistance, insect resistance and disease resistance;
- (b) selecting F1 progeny plants that have the desired trait to produce selected F1 progeny plants;
- (c) crossing the selected progeny plants with the DP 494 RR plants to produce backcross progeny plants;
- (d) selecting for backcross progeny plants that have the desired trait and physiological and morphological characteristics of cotton line DP 494 RR listed in Table 1 to produce selected backcross progeny plants;
- and
- (e) repeating steps (c) and (d) three or more times in succession to produce selected fourth or higher backcross progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of cotton line DP 494 RR listed in Table 1 as determined at the 5% significance level when grown in the same environmental conditions.
