In the present investigation, variability induced by ethylmethane sulphonate (EMS) for four quantitative traits viz., fertile branches/plant, pods/plant, 100-seed weight (g) and yield/plant (g) was studied in M2 and M3 generations of green gram (Vigna radiata L. Wilczek) var. Asha. A significant shift in mean values in the positive direction was observed for all the quantitative traits studied. High values of heritability and genetic advance over the control indicate the possibility of inducing desirable mutations for polygenic traits accompanied with effective selection in M2 and later generations. Yield/plant was positively correlated with various yield contributing traits, but did not show any association with seed protein content.
