Abstract

The experiment was carried out during rabi 2019-2020 at Crop Research Farm, Nawabganj of C.S. Azad University of Agriculture and Technology Kanpur, Uttar Pradesh (INDIA) for experiment. The experimental materials comprised of 100 treatments including 10 diverse parents, 45 F1s and 45 F2s were planted in randomized complete block design with three replications. Path analysis considered one of the best statistical methods which can help breeders to characterize the crop populations during the parent selection program and select the desirable genotypes for higher yield production. Path coefficients analysis showed that biological yield per plant has maximum and positive direct effect on grain yield per plant followed by number of tillers per plant at phenotypic level. Harvest index, plant height, seed hardness, tryptophan content, number of seed per spike and 1000 grain weight per plant had also positive direct influence on grain yield per plant. Rest of the traits has negative direct influenced grain yield per plant.
