Mutagenic effectiveness and efficiency of gamma-rays, ethyl methane sulphonate and their synergistic effects in black gram (Vigna mungo L.)

Mutation frequency, effectiveness and efficiency of gamma-rays, ethyl methane sulphonate (EMS) and synergistic effects of their combination treatment were assessed in T-9, an improved variety of black gram. Gamma-rays were more effective than EMS. However, EMS was 2-2.5 times more efficient than gam...

More Information
Summary:Mutation frequency, effectiveness and efficiency of gamma-rays, ethyl methane sulphonate (EMS) and synergistic effects of their combination treatment were assessed in T-9, an improved variety of black gram. Gamma-rays were more effective than EMS. However, EMS was 2-2.5 times more efficient than gamma-rays. There was a progressive increase in mutation frequency of chlorophyll and viable mutations with the increase in gamma-rays and EMS doses. Synergistic effects were observed for increasing mutation frequency in M2generation in combination treatment of gamma-rays with EMS.
