Abstract:
The present research work was conducted at Crop Research Farm, Nawabganj, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.), India. The experimental material for present investigation comprised of 100 treatments including 45 F₂s, 45 F₁s and 10 parents viz., DBW-88, K-1313, DBW-107, K-9423, DBW-90, HI-8699, DBW-14, K-1006, HD-3059 and HD-2967 were evaluated in RBD followed by half diallel mating design for the study of correlation and path coefficient analysis for fifteen characters, namely, days to 50 per cent flowering, plant height, days to maturity, number of productive tillers per plant, flag leaf area, spike length, number of spikelets per spike, number of grains per spike, biological yield per plant, grain yield per plant, 1000-grain weight, harvest index, protein content, phenol colour and seed hardness in wheat. The study of correlation revealed that grain yield per plant strongly associated with number of productive tillers per plant and biological yield per plant in both F₁ and F₂ generation at both genotypic and phenotypic level. Path analysis revealed that 1000 grain weight, biological yield per plant, harvest index, seed hardness and protein content showed positive direct effect on grain yield per plant in both F₁ and F₂ generation at both genotypic and phenotypic level.
