Induced mutations in barley by gamma rays and ethyl methansulfonate

Gamma rays and ethyl methansulfonate (EMS) were used to iduce useful mutations in local black barley.Thirteen mutants were selected during the first three generations.Mutants HBB-1.HB-4 and HBB-2 and HBR-3 showed considerable reduction in plant height,while mutants HBR-88,HBR-95 revealed significant increse in weight of 100 spikes.seed weight,weight of 1000 kernels and earliness in heading and maturity by more than 3 weeks.Mutants HBB-1 and BB-10 showed resistance to powdery mildew and lodging along with compaetness in ear structure.Mutants HBR-2,HBR-3 and BB-123 showed to lerance to drought condition.Allselected mutants showed significant genetic stability in their traits at M3 and M4 generation.(3 tabs., 14 refs.)
