    This experiment has been conducted based on the biometrical technique (half diallel) suitable for making possible combination with different genotypes based on their sowing pattern like timely sown, late sown, timely sown with irrigated and late sown with rainfed condition with genotypes for present investigation comprised of forty five F1s developed by crossing 10 lines viz., DBW187, K1601, HD2967, HD3249, DBW321, K1317 K0307, HI 1563, DBW107 and HD3059 following half diallel mating design. The cross combination HD2967X K0307 and K0307X K1601 with the cross HD2967X K0307 with positive and significant values was in the order of merit for grain yield per plant

    An experiment was conducted to estimate the genetic variability, heritability and genetic advance in the 100 wheat genotypes including ten parents and 45 F1 and 45 F2 for obtained through half diallel mating design in Wheat during 2021-22 at Oil Seed Farm, Kalyanpur, C.S. Azad University of Agriculture and Technology, Kanpur-208002 (U.P.) Quantitative analysis were carried out for all the parameters which are directly or indirectly associated with the yield and yield contributing traits. Analysis of variance showed significant variability for all the studied characters for parents.  In F1 significant variability was observed in all the traits except spike length, number of grains per spike and protein content reflecting considerable amount of heterotic response in these attributes. High heritability was observed in all the characters in F1 and F2 in both the generations. Highest value of GCV and PCV were observed for grain yield per plant (20.01) in F2 indicating the presence of high genetic variation. High heritability coupled with high genetic advance for protein content and yield per plant which indicate the presence of additive gene action and used for future population improvement. The genotypes with specific characters could be utilized for hybridization programme
