Fifty germplasm of bread wheat used to study the nature and magnitude of genetic divergence using Mahalanobis’s D2 statistics. The data for twelve important quantitative traits recorded from the genotypes raised in Randomized Block Design having three replications. The fifty genotypes were grouped into eight clusters. Cluster I was largest with fourteen genotypes followed by cluster IV with ten genotypes. The maximum inter-cluster distance was observed between cluster II and III, suggesting that the genetic architecture of the genotypes in one cluster differ entirely from those included in other clusters. Noteworthy is that cluster IV exhibited high cluster means for days to 50% flowering; cluster VIII for plant height and cluster VI for spike length. Among the twelve traits studied, maximum contribution was made by number of effective tillers per plant contributed maximum divergence (12.84%) followed by number of spikelets per spike (11.24%), length of spike (11.05%), biological yield per plant (10.15%). Therefore, these characters may be given importance during hybridization program.
