The present investigation was carried out for two years during kharif season (2012 and 2013) of 28 rice genotypes including 2 local checks and layout in Randomized Complete Block Design (RBD) with 3 replications under irrigated condition. Nature and magnitude of genetic divergence was assessed using Mahalanobis D2 statistics through which the genotypes were grouped inti 6 clusters. In the first year cluster III having 13 genotypes whereas, in next season cluster I containing of 12 genotypes was largest. While cluster V, VI during 2013 were found monogenotypic clusters. The highest inter-cluster divergence (74.537) was found between cluster I and IV in the year 2012 and cluster II and III (79.081) in 2013. Thus, the genotypes selected from cluster I (C-1446-5-18-17-1-MLD-2, JGL-1718, WGL-365, UPR-3411-1-1-1, UPR-3305-6-1-2, CR-77-3-1-1, NP-14-3-1, GontraBidhan-3, UPR-3027-10-1-1) for number of productive tillers, cluster IV (UPRI-3425-14-3-1, UPR-3443-7-2-1, NP-218, KAGR-559-1) for number of grains per panicle and cluster VI (Pant Dhan 4) for panicle length and grain yield per plant could be used in crossing programmes to achieve desired segregants.
