Analysis of yield components and their association for enhancing grain yield in bread wheat (Triticum aestivum L. em Thell.) under sodic soil

Experiment was conducted to assess direction, magnitude of association of different characters and contribution of various traits on yield for 96 (72 crosses+ 22 parents+ 2 standard checks)wheat genotypes in which grain yield was assumed as dependent character. The variation due to checks was signicant for all the character. Highly signicant and positive correlations were exerted in case of biological yield followed by harvest index while significant and positive association was observed for chlorophyll content, tillers per plant, plant height, flag leaf area. Path-coeffcient analysis revealed that biological yield has high order of direct positive effect followed by test weight and chlorophyll content while other traits exhibited very low or negative direct effect on grain yield. The characters identified above can practiced for obtaining high yielding cultivar.
