 ABSTRACT

An experiment was conducted during kharif, 2012 to access genetic variability among fifty eight mungbean genotypes for yield, yield attributes and drought related traits under irrigated and moisture stress conditions. Analysis of variance revealed that significant differences among the genotypes for all the characters studied except relative water content. Estimates of phenotypic co-efficient of variation (PCV) were higher than genotypic co-efficient of variation (GCV) for all the characters. High to moderate GCV estimates and high heritability coupled with high genetic advance as per cent of mean were observed for relative injury, number of branches per plant, number of pods per cluster, specific leaf area, 100 seed weight, plant height, harvest index, SCMR and seed yield under both irrigated (E1) and moisture stress (E2) condition suggesting that involvement of additive gene action for these characters. Hence, simple directional selection could be considered for these characters in the segregating generations to improve seed yield with drought tolerance.

Key words: Mungbean, Genetic variability, Heritability, Irrigated and Moisture stress conditions
