Mutagenesis has been widely used as a potent method of enhancing genetic variability for crop improvement. The variability induced by ethylmethane sulphonate (EMS) and hydrazine hydrate (HZ) for four quantitative traits viz., fertile branches per plant, pods per plant, 100-seed weight (g) and total plant yield (g) was evaluated to find out the selection response in M2 and M3 generations of mungbean \Vigna radiata (L.) Wilczek] var. NM-1. The mean values for yield and yield components increased significantly with all the treatments in both the generations. The genotypic coefficient of variation, heritability and genetic advance increased manifold in the treated population indicating that these traits are controlled by additive genetic variance and selection would be effective. Increase in mean values coupled with an increase in genetic variability for yield attributing traits suggests further possibilities of selecting more promising lines with high yield potential.
