This investigation records the results of 8 × 8 diallel mating design for grain protein and sedimentation value in wheat. General and specific combining ability variances were highly significant. Additive genetic component appeared to be of more importance compared to dominance component for protein content. Component analysis for sedimentation value gave upward biased estimate of dominance component H,. Narrow sense heritability estimates were high (54–88% for protein and 51–12% for sedimentation value). High protein was primarily under recessive genes while reverse was true for the sedimentation value. UP 302 and NP 852 were common good general combiners for increasing the protein and the sedimentation value and possessed mostly recessive and dominant genes respectively. The results suggested the scope for selection.
