Increased Genetic Variability for Total Plant Yield in M3 Generation of Mungbean

A work was carried out to investigate the yield and yield components in the two varieties of mungbean namely Asha and K-851 in M3 generation. The total yield per plant, shows that there was a general increase in the mean values for each treatment in both the varieties. The mean value in the treated population significantly varies as compared to the control. The phenotypic and genotypic coefficient of variation, heritability and genetic advance increased in both the varieties after the mutagenic treatments. The increase in the phenotypic coefficient of variation and the genetic parameters was higher with 0.2% EMS treatment in the variety K-851
