Abstract: Beside rich biodiversity, Odisha is having a potential source of indigenous gene pool of several crops. In Odisha land races of blackgram are sources of valuable genes which provide tolerance to various biotic and abiotic stresses, hence characterization and evaluation of such local germplasm may provides useful materials for breeding of good varieties. A throughout knowledge of existing genetic variation and degree of association among yield and yield contributing traits are essential for developing high yielding genotypes in blackgram. In this present investigation yield plant-1 contributed maximum towards divergence. The genotypes belonging to different clusters are havingshowed maximum divergence for different characters and may be successfully utilized in hybridization programmes to get desirable transgressive segregants. It is assumed that maximum amount of heterosis will be manifested in cross combinations involving the parents belonging to most divergent clusters with wide inter cluster distance....
