A study was conducted to estimate the extent of heterosis for yield and its quality traits in 56F1s developed from 16 diverse parents by partial diallel mating design in wheat (Triticum aestivum L.). The experimental material comprised of 56 F1 crosses along with their 16 parents conducted at three different environments. Economic heterosis on pooled basis ranged from −8.32 to 35.42 percent for grain yield, −4.12 to 20.77 percent for protein content, 3.61 to 30.12 percent for tryptophan content, −20.65 to 37.93 percent for seed hardness and −12.98 to 22.64 percent for 100 grain weight. Among them two crosses K7827/K7503 and K7229/K7503 showed positive and significant response for grain yield at all the locations.
