The present study was carried out to estimate the genetic parameters on sixteen morpho-physiological traits with thirty-one mungbean genotypes. The results revealed that based on the per se performance, the genotypes LGG 450 and MGG 350 showed superior performance for yield as well as drought tolerance traits suggesting that these genotypes could be exploited in the breeding programme to develop drought tolerant lines coupled with high yield. High to moderate GCV estimates and high heritability with high genetic advance as per cent of mean were observed for number of pods per plant, 100 seed weight, relative injury, chlorophyll stability index, specific leaf area and chlorophyll content indicating that the variation in the above characters most likely due to additive gene effects, hence simple directional selection may be effective to improve these characters.
