VARIABILITY STUDIES IN M3 GENERATION IN BLACKGRAM (VIGNA MUNGO (L.)HEPPER)

Abstract

In the present study, pure line seeds of black gram variety viz. T-9, TPU-4 and one promising genotype AKU-18 was treated with gamma irradiation (15kR, 25kR and 35kR) with the objective to assess the variability in M₃ generation.. Highest GCV and PCV and high estimates of heritability were recorded for the characters sprouting percentage, number of pods plant^-1 and grain yield plant^-1 (g). High heritability accompanied with high genetic advance was recorded for number of pods plant^-1 governed by additive gene effects and therefore selection based on phenotypic performance will be useful to improve character in future.
