Abstract
The experiment was conducted to determine the direct and indirect effects of the some yield attributing traits like plant height, bolls. plant-1 , boll weight, seed index, lint index and ginning outturn on seedcotton yield per hectare. The experiment was carried out in randomized complete block design with twelve genotypes during 2014-15 at Central Cotton Research Institute Sakrand. Analysis of Variance revealed that all genotypes significantly differ from each other for all the recorded traits which were further grouped by the least significant difference. Seedcotton yield per hectare showed highly significant positive genotypic and phenotypic correlation with bolls. plant-1 (0.984, 0.982) and with boll weight (0.490, 487). Plant height also showed highly significant negative genotypic and phenotypic correlation with seed index (-0.526, -0.522). Plant height Seed index, lint index and ginning outturn showed non significant genotypic and phenotypic correlation with seedcotton yield per hectare. Bolls. plant-1 had maximum direct effect (0.945) followed by the boll weight (0.062), seed index (0.007), lint index (0.040) and plant height and ginning outturn had negative direct effect (-0.119 and -0.014) to the seedcotton yield per hectare.
