The effects of different doses of gamma rays (0, 10, 20 and 30 kR) and ethyl methane sulphonate (EMS) (0.4, 0.6 and 0.8 %) on mutagenic induced in soybean cv. JS 97-52, MAUS-47 and JS 97-52 x MAUS-47 were investigated. The sensitivity response of soybean to gamma radiation and EMS was determined based on seed germination, plant survival and growth reduction in the M1, F1M1 generation. In the present investigation, variability induced by gamma rays and EMS for ten quantitative traits of soybean was studied. A significant shift in mean values in the positive direction over control was observed for most of the quantitative traits in all the populations, while in some cases particularly at higher doses; the decrease in mean values was noticed. The estimates of coefficient of variability for all the characters were high in all the mutagenic treatments. The high coefficient of variability was also accompanied by moderate to high heritability and genetic advance as percent of mean for different characters in various mutagenic treatments. Therefore, phenotypic selection for different characters will be effective in the treated population.
