Combining ability studies were conducted in 9X 9 half diallel fashion in quality protein maize (QPM) at Agricultural Research Station, Ramnagar, Adilabad during Kharif, 2015 to determine GCA and SCA effects of parents and single crosses respectively. The overall study indicated that the parents, QPM-39, QPM-45, QPM 10057-2, QPM-10-1 and QPM-15 can be considered as good general combiners and genetically worthy parents, as they contributed favourable genes for grain yield and its components at all the three locations and in pooled analysis. Combining ability analysis revealed that the parents, QPM 58, QPM-45, QPM-3-3, QPM-39 and QPM-15 were found to be good general combiners for earliness. The parent, QPM-39 and QPM-45 were good general combiners for grain yield, days to 50 per cent anthesis, days to 50 per cent silking, days to maturity (all towards earliness), ear girth, ear length, number of kernels per ear, number of kernels per row, 100-kernel weight, shelling percentage. In addition, QPM-45 was a good combiner for tryptophan and lysine contents.
