Sixty five wheat accessions were evaluated for yield and related traits during winter 2010-2011. Highly significant (P≤0.01) differences were found for all the traits studied indicating the scope of improvement through simple selection for high mean values of these traits. Maximum genotypic differences were observed for all the studied parameters except chlorophyll concentration index and number of spikelet per spike indicating considerable amount of variation among the accessions for each trait. The genotypic and phenotypic coefficient of variation estimates were higher for all the traits except chlorophyll concentration index and days to physiological maturity. Highest heritability estimates and expected genetic advance were found for all the traits except chlorophyll concentration index, spike length and number of -1 spikelet spike which exhibited moderate heritability. Based on Euclidian dissimilarity distance, 65 wheat accessions were classified in to 6 different clusters. Maximum diversity was found in cluster 1 and cluster 4. This maximum diversity explains the better parental selection for future breeding programme.
