The nature and the magnitude of genetic divergence was estimated in forty-eight germplasm of rice during two season Kharif 2017-18 and Kharif 2018-19using Mahalanobis’s D2-statistics. The genotypes were grouped into 10 clusters showing a reliable degree of relationship between geographic distribution and genetic divergence. During Kharif 2017-18,Cluster II showed maximum intra cluster divergence and inter cluster divergence was maximum between clusters IX and X while in Kharif 2018-19, maximum intra cluster distance was exhibited by cluster VI and maximum inter cluster distance was between clusters VIII and X. All the minimum and maximum cluster mean values were distributed in relatively distant clusters. Traits like plant height, total grains per panicle and test weight contributed maximum towards divergence.
