Range, mean and cofficient of variation for different characters in two cultivars, namely, PDUI and T9 of urdbean suggested that the mutagenic treatments had wider values than control. Positive and negative shifts in mean were observed for all the quantitative traits in both the cultivars. All the mutagenic treatments influenced the mean, range and CV values independently in both the varieties. However, the combination of varying doses of gamma rays with EMS (0.02 M) was found effective for causing induced genetic variability in urdbean cultivars.
