Genotypes]]>IqbalKhalid Mohammad Aslam Chowdhary 7200037Combining ability studies were performed for plant height, spike length, number of spikelets per spike, number of grains per spike, grain weight per spike and 1000-grain weight in a set of diallel crosses involving five spring wheat genotypes. Significant variation was found in all six characters. General combining ability (GC), specific combining ability (SCA) and reciprocal effects were significant. Additive gene action was found for the characters under study. Best general combiners and the best cross combinations were identified for future breeding programme.]]>Chowdhry, M.A., M.T. Mahmood, N.
