Narrative
Mean, range, and sample variance statistical parameters were used to compare the mutants with their parents. Line charts from 150 random individual plants from the mutant and check variety indicated that there was a shift in means to the right for the mutant for fiber length and strength indicating an improvement of these traits in the mutant. The ranges of the mutant in fiber length, fiber strength, lint percent, and seed index were wider for the mutants. In 2010, significant differences in the sample variances were observed for fiber length, lint percent, micronaire, and seed index for the MD 15 M4 mutants and the check cultivar. Higher variances were accompanied by wider ranges for the mutant as compared to the check parent, MD 15. Overall, chemical mutagenesis appeared to have created new extremes at both the low and high ends for fiber length, fiber strength, lint percent, micronaire, and seed index. Cotton breeders and geneticists can exploit this new variability in their cotton improvement programs. This is relevant in light of the narrow germplasm base currently observed in cotton germ plasm which limits the success of breeding programs.

Pedigree
Description:
About 5000 seeds of the Delta cultivar MD 15 were treated with 3.2 % Ethyl methanesulfonate (EMS) in 2008. The mutagenized seeds were immediately hand planted in the field and one boll per plant harvested from the surviving 40 % plants to form the Ml population at Lubbock, TX. The Ml was planted in the field in 2009, M2 in 2010, and M3 in 2011 at Stoneville, MS following similar procedures to reduce the mutation load. Random samples from the mutant and its non-mutated parent were planted in 2004 in replicated tests in two environments to test the value of the mutant population. One boll per plant bulks from the M4 of the mutant population is available for registration as MD 15 M4.
