Heritability and Correlation Studies of Yield and Yield Related Traits in Bread Wheat

A set of 27 genotypes were tested for estimation of heritability, genetic advance and association of yield and yield related traits in wheat. For all the studied traits, mean squares showed the presence of significant variation (p≤0.01) among the genotypes. Heritability estimates were observed high (h²˃0.60) for all the traits. The highest heritability (0.93) was noticed in plant height followed by flag leaf area (0.89). The values of genetic advance were recorded low to moderate for all parameters. Grain yield was observed to have positive significant association with most of the important yield related traits such as fertile tillers, spike length, 1000-grain weight and grains per spike. These results suggest that all the traits showing significant correlation with grain yield needs better attention in future wheat breeding programs for increasing yield.
