The experiment was conducted to the study of combining ability and heterosis over better parent and economic parent (HD-3987) in bread wheat. Hybrids were formed using half diallel (7x7) mating design conducted in Rabi 2017-2018 and 2018-2019 at Research Farm, Department of Genetics and Plant Breeding, School of Agriculture, Lovely Professional University, Phagwara. The results revealed that non-additive genetic variance played a predominant role in the inheritance of all the traits. The best combinations mostly involved good x poor and poor x poor general combiners for the characters under study. There was very rare case in which good x good general combiners were involved for best combinations. On the basis of gca and sca effects, 3 cross combinations were found specific combiners for higher grain yield/plant and also for various yield contributing traits, respectively. Top 5 crosses were HI-1544 X LOK-1, MP-3173 X HD-2932, MP-1203 X HD-2932, MP-3173 X LOK-1 and MP1203 X MP-4010 on bases per se performance of grain yield/plant.
