Abstract: 34 genotypes collected from various sources were grouped into six clusters following Mahalanobis D² statistics. Cluster III was the largest (12 genotypes) followed by clusters II (eight), VI (Six) and VI (four). The maximum intra-cluster distance was observed in cluster III, II and V suggesting that genotypes are having diverse genetic architecture. The inter-cluster distance was high between clusters V and VI there by indicating wide range of variation among the clusters. The per cent contribution towards genetic diversity was high in 100 seed weight (59.00%), days to 50 % flowering (15.15%) and days to maturity (11.94%), Selection pressure on these traits may lead to an overall increase in grain yield per plant. The inter-cluster representatives of distant clusters would be more useful for choosing the parents in hybridization programme.
