Description:
A cotton germplasm (MD 15) was treated with 3.2% v/v ethyl methanesulfonate (EMS). Seeds were imbibed in aerated distilled water for 16 h and rinsed and treated with EMS for 2 h. Seeds were hand planted in 2008 to produce the M1 plants. From 2008-2012 one boll per plant was harvested in bulk to form the next generation and reduce the mutation load. During 2013-16 replicated tests identified MD 15-Mut 13, MD 15-Mut 31, MD 15-Mut 61, MD 15-Mut 89 and MD 15-Mut 138 for their superior quality.
