Three mutagens, i.e. sodium azide (SA), ethylmethane sulfonate (EMS) and gamma radiation (GR), were employed to induce genetic variation in chickpea cv. Vishwas. Different kinds of mutations, i.e. chlorophyll mutations (chlorina and xantha), leaf mutations (round, curly, gigas, compact and narrow), pod mutations (large, long, small roundish, narrow elongated and small), seed mutations (wrinkled, bold, dark brown and bold dark brown), flower mutations (2 tier and open) and morphological mutations (bold seeded, small pod, early and tall), were observed in the M2 generation. Induced mutant lines showed both positive and negative increase in the quantitative traits. Tall mutant lines obtained after 16 mM EMS treatment was the tallest with increase in number of pods and number of seeds. Mutagenic treatments also caused changes in seed size and seed coat. Variations were observed for crude protein, globulin and albumin contents in the mutants. The highest heritability coupled with high genetic advance was observed for quantitative traits, such as plant height and number of pods/plant, for the mutants of chickpea cv. Vishwas.
