Abstract

The mutagenic effects of gamma rays (10, 20, 30 and 40 kR) and ethyl methane sulphonate (0.01, 0.02, 0.03 and 0.04M) alone or in combination (lOkR + 0.02M, 20kR + 0.02M, 30kR + 0.02M and 40 kR+ 0.02M) on frequency and spectrum of chlorophyll and macromutations in two cultivars, namely, PDUI and 1'9 of urdbean have been observed. Conclusively, the combination treatments have yielded the his!ter frequency and spectrum of chlorophyll mutations whereas the various doses of mutagenic agents have independent response towards macromutations in both the cultivars.
