Genetic divergence was studied for different yield and quality component traits for 54 rice genotypes. The analysis of variance revealed presence significant differences among the genotypes for all the characters studied. Based on genetic distance all the 54 genotypes were grouped under nine different clusters. The mode of distribution of genotypes from different eco- regions into various clusters was at random indicating that geographical diversity and genetic diversity were not related. The characters like zinc content, iron content, amylose content and grains per panicle contributed maximum towards genetic diversity. The maximum inter-cluster distance was recorded between cluster III and V. Selection of genotypes in these clusters which may serve as potential donors for future hybridization programmes to develop potential recombinants with high yield coupled with different quality traits.

Key words: Rice, Genetic divergence, D2 analysis, Quality traits
