Abstract

The present study was carried out to access 50 semi arid wheat yield trials of CIMMYT including 1 check (HI-1544). The experiment was laid down in randomized block design during rabi season of 2020-21. The divergence studies revealed that fifty genotypes are clustered into six clusters with maximum genotypes in cluster I viz. forty five and all other five clusters (Cluster II, III, IV, V, VI) were solitary. The highest intra-cluster distance was observed for cluster I. Hence, genotypes belonging to the cluster I may be utilized as parents in future breeding programme with the genotypes belonging to cluster III as the maximum inter-cluster distance was noted between the cluster III and Cluster V. This showed that a hybridization programmes including parents from these clusters would result in a higher frequency of better segregates or desired combinations. Maximum genetic divergence was found for seed yield per plot, followed by biological yield per plot, harvest index and number of seeds per spike.
