A 5 x 5 diallel cross experiment was carried out at the University of Agriculture, Faisalabad during 1997-98, in wheat to determine the mechanism of gene action responsible for the inheritance of plant height, yield and some important yield components. Plant height and spike density was verned by partial dominance with additive type of gene action. Spike length, number of grains per spike and grain yield per plant was controlled by over dominance type of gene action. Maximum number of dominance genes was present in line 8244 for most important characters, like number of grains per spike and grain yield per plant. The genotype 8244 possessed maximum array mean for number of grains per spike, while the genotype 243/1 had maximum array mean for grain yield per plant. From this discussion it could be concluded that selection for plant height and spike density would be effective in early generations for this material, while selection for spike length, number of grains per spike and grain yield per plant would be ineffective in early generations. No epistatic effects were found for all the traits under discussion.
