Abstract: Two hundred germplasm accessions of Green gram [Vigna radiate (L.) Wilczek] were screened for drought tolerance using augmented design. Augmented ANOVA revealed highly significant mean squares attributable to germplasm accessions for all the traits. Mean squares attributable to ‘Genotypes vs check entries’ were significant for all traits except seed per pod and relative water content. The correlation coefficient analysis revealed that out of 17 independent variables studied, 15 variables showed positive correlation with dependent variable yield. Two variables namely days to 50 per cent flowering and days to maturity did not show positive correlation with yield. Among the independent variables, pods per cluster had highest positive correlation with seed yield per plant (0.84) followed by pods per cluster (0.77) clusters per plant (0.71), plant height (0.68), proline content (0.63), spad chlorophyll meter reading (0.62), leaf water potential (0.61), harvest index and seeds per pod (0.60).
