Abstract

Forty nine genotypes of wheat including two of triticale were studied for genetic divergence utilizing Mahalanobis D2 statistics. These genotypes were grouped into five clusters of which cluster III was the largest accommodating 31 genotypes and it was followed by cluster I with 9 genotypes. Inter cluster distance was maximum between cluster V and IV indicating presence of most divergent genotypes within these clusters. Means of some important characters like plant height (cm), number of spikelet spike-1, weight of grain spike-1 (g), 1000 grain weight (g) and grain protein (%) were found to be highest in cluster II which also maintained high magnitude of genetic distance with cluster IV. So, genotypes belonging to cluster II, IV and V can be used for further improvement of different traits along with yield.
