Abstract
Mutation frequency, effectiveness and efficiency of gamma rays, ethyl methane sulphonate (EMS) and synergistic effect of their combination treatments in relation to induction of chlorophyll and viable mutations was made in two different genotypes of mungbean, namely, T 44 and PDM 54. The studies revealed that ethyl methane sulphonate (EMS) was found to be more effective in inducing mutations than gamma rays. However, EMS was 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 in both the cultivars. Synergistic effects were observed for increasing mutation frequency in M-2 generation in combination treatments of gamma rays with EMS. Both mutagenic effectiveness and efficiency were found to be higher at lower doses of both the mutagens. Varietal preference to mutagens was also noticed in the present study.
