The present investigation embodies the results of variability in induced mutants in greengram cultivar K-851 exposed to X-rays, ethylmethane sulphonate, diethyl sulphate at various doses singly and in combination. Variance due to progenies were significant for all the traits viz. pod length, No of seeds/pod and 100 seed weight. Negative shift in mean values for all the characters except for the grains per pod and 100 seed weight was observed. However, increase in components of genotypic and phenotypic variance, genotypic coefficient of variation, heritability and genetic advance was observed in low to high range for pod length and grains per pod while low to mederate for 100 seed weight. The changes observed were not mutagen and dose specific.
