The present investigation was conducted with 36 genotypes of mungbean on 26 agro-morphological traits including seed yield and pubescence traits to access the degree of divergence for mungbean improvement during zaid 2012. These mungbean genotypes were grouped into seven clusters. Cluster IV comprised of 14 genotypes, forming the largest cluster followed by cluster VI comprised eight genotypes, cluster I comprised seven genotypes and cluster II comprised four genotypes. Three clusters viz., cluster III, V & VII formed mono genotypic cluster. All the pubescence traits contributed towards total divergence. Among the agro-morphological traits, high contribution towards total divergence was recorded for beak length, average intermodal length, primary branch angle with main stem, biological yield, seed yield and pods per cluster, indicated the possibility of selection of parent(s) for hybridization to manipulate the targeted trait(s) for mungbean improvement.
