  • Abstract:
  • A study has been conducted to estimate the essence and the extent of genetic divergence of 50 rice genotypes, on the basis of 19 agro-morphological traits following Mahalanobis’ D2 statistics. The genotypes were grouped based on D2 values into eight cluster’s following Tocher’s method. Five multi-genotypic and three mono-genotypic clusters were found after grouping by Tocher’s Method. The most divergent clusters were cluster IV and VIII (D2= 24.81) followed by VII and VIII (D2=21.98) and II and VIII (D2= 20.62). Highest intra-cluster distance was observed in cluster VI followed by cluster V. Cluster I was the largest one containing 24 genotypes. Thus the genotypes belonging to the cluster II, IV, VII and VIII having highest cluster distance are suggested for incorporation in hybridization program because they are predicted to produce desired segregates.
