GAMMA RAY AND EMS INDUCED GENETIC VARIABILITY FOR QUANTITATIVE TRAITS IN URDBEAN (VIGNA MUNGO L. HEPPER)

Published on

Range, mean and coefficient of variation for different characters in two cultivars,
namely, PDUI and 1'9 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.
