Fifty-eight genotypes of rice were studied for genetic diversity on the basis of yield and its attributing traits. Based on D2 analysis, 58 rice genotypes were grouped into eight clusters. Cluster II consisted maximum of 16 genotypes followed by cluster III with 11 genotypes. Among different traits, test weight followed by days to 50% flowering, filled grains per panicle and plant height had maximum contribution towards the total divergence. PCA identified four components with eigen value more than one which contributed 85.028 percent of cumulative variance. Divergence studies indicated that selection for hybridization should be more based on genetic diversity rather than the geographical diversity
