Uniformity index above 85 is ‘very high’ (USDA Agricultural Marketing Service, 1995). Mutations in upland cotton strains that exhibit fiber length ≥32 mm and fiber bundle strength ≥420 KN m kg-1 are unique. The mutants MD 15-Mut 13, MD 15-Mut 31, MD 15-Mut 61, MD 15-Mut 89 and MD 15-Mut 138 have unique, extra-long, very strong and very highly uniform fibers. MD 15-Mut 31 had fiber length that was 10 percent longer than that of the fibers of MD 15 and 12 percent longer than that of MD 10-5. MD 15-Mut 89 and MD 15-Mut 13 both had fibers that were 6 percent longer than MD 15 and 8 percent longer than MD 10-5. MD 15-Mut 61 and MD 15-Mut 138 had 4 percent longer fiber than the check germplasm,10-5. In terms of fiber strength, all five mutants had very strong fibers. The mutant MD 15-Mut 31, had superior performance in fiber strength. It had fiber strength which was 12 percent higher than MD 15 and 23 percent higher than MD 10-5 The other four mutants had 4 to 9 percent higher fiber strength than MD 10-5 and 14 to 20 percent higher fiber strength than MD 10-5. All fiber mutants showed very high fiber uniformity which ranged from 86 to 88 percent. The 2015 Regional High Quality (RHQ) test at Stoneville, MS indicated that MD 15-Mut 31 and MD 15-Mut 89 had higher fiber length and strength than the national checks ‘PHY 725RF’ and ‘FM 2484B2F, the local check varieties MD 10-5 and MD 87 and the other 16 breeding lines in the test. Cotton breeders can incorporate the superior fiber quality from these mutants into high yielding germplasm to suit their local conditions. These characteristics may allow the development of cotton cultivars that could be utilized in higher value textile markets increasing the economic competitiveness of cotton producers in the US. | 1947846 | PI 681709 |
