Vigna mungo (L.) Hepper commonly known as black gram is an important pulse with high protein value cultivated through out India. Ten genotypes of Odisha and three released check varieties of black gram were analyzed for genetic diversity using agronomical characters and RAPD markers. Yellow Mosaic Virus (YMV) % showed significant variation of 1% to 85% of infection among the black gram genotypes. Cluster analysis of agronomic characters showed sub-cluster-I with high (~3.0% YMV) and sub-cluster-II with moderate resistance (~15.5% YMV) forming cluster-I. The highly susceptible TAU-1, Kaska local and Balangir local separating as cluster-II. A total 47.98% bands were polymorphic out of the 189 RAPD bands amplified. RAPD analysis showed cluster-I and cluster-II consisted of 10 genotypes and 3 genotypes respectively. Highly susceptible (sub-cluster-I) and moderately susceptible (subcluster- II) formed a cluster-I. All the high resistance four varieties namely Deogan local, Cheripalli local, Pendibari local, Kendr para local (1% to 3% YMV) formed cluster II showing resistance and grain yield like of TU942, a released check variety. Thus, RAPD could distinguish a separate resistance varieties of Odisha genotypes recommended for breeding programme. Genetically heterogeneous group sub-cluster II of cluster I genotypes might the potential breeding partner to cross with susceptible varieties of sub- culture I of cluster I for black gram genetic improvement.
