An experiment with thirty three genotypes of bread wheat carried out to study the nature and magnitude of divergence using Mahalanobis D2 statistics, in randomized block design with three replications. The data for thirteen important quantitative traits were recorded from the genotypes raised. The variability study indicated high to moderate phenotypic and genotypic coefficient of variation accompanied by high heritability and genetic advance as per cent of mean for traits, plant height, number of tillers per plant, flag leaf area, chlorophyll content, canopy temperature, spike length, grains per spike, grain yield per plot and harvest index indicating their importance in selection for yield improvement. The thirty three genotypes of bread wheat were grouped into six clusters using Tocher’s method. The genotypes in cluster III and cluster VI, exhibited high degree of genetic diversity. Cluster I was suitable for spike length, flag leaf area, grains per spike, thousand grain weight, and grain yield per plot. Days to fifty per cent flowering and harvest index contributed maximum towards genetic divergence.
