Thirty genotypes of bread wheat (Triticum aestivum L.) evaluated for yield and other related characters. Six characters i.e. plant height, effective tillers per plant, grain yield per plant, spike length, grains per spike and 1000 grain weight exhibited high variability. The remaning traits shows moderate to low variability. Following the Mahalanobis D2 analysis, all the thirty genotypes were grouped into six clusters. On the basis of the data on genetic divergence and mean performance of yield and other traits, diverse and superior genotypes namely, HUW 533, K 68, K 9465, K 65, K 816, HD 2891, HD 2643, HD 2687, HD 2824, PBW 343, HD 2733, Kalyansona and Sonalika. Were selected to involve in multiple crossing programme to recover transgressive segregants. Further, on the basis of cluster means, cluster VI has been identified for selecting parents for incorporating grain yield per plant, tillers per plant and plant height, cluster V for spike length, grains per spike and early maturity and cluster III for 1000 grain weight. On the basis of character associations, it is argued that selection of plants.
