Abstract:
An experiment was conducted to determine the genetic variability, heritability, genetic advance and direct and indirect effect for yield and its component traits in 40 wheat genotypes under irrigated condition. Phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the characters under studied. Plant drooping height exhibited highest GCV and PCV estimates followed by number of tillers per meter, flag leaf area, seed density and harvest index. Plant drooping height, number of tillers per meter, flag leaf area, arvest index, flag leaf length and seed density exhibited high genetic advance as per cent of mean along with high heritability estimates. Path analysis showed that thousands grain weight had highest positive direct as well as indirect contribution toward grain yield via grain weight per spike followed by flag leaf area followed by harvest index, flag leaf area and biological yield
