MUTAGENIC EFFECTS OF GAMMA RAYS AND EMS ON FREQUENCY AND SPECTRUM OF CHLOROPHYLL AND MACROMUTATIONS IN URDBEAN (VIGNA MUNGO L. HEPPER)

Published on

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.
