The experiment was conducted to evaluate and select strains/varieties of wheat in terms of their genetic values and also to make selection criteria for further breeding program. Mean squares for general combining ability were highly significant for flag leaf area, number of fertile tillers per plant and significant for spike length while non-significant for plant height and peduncle length. Specific combining ability mean squares were highly significant for plant height, number of fertile tillers per plant and peduncle length, while non-significant for flag leaf area and spike length. Mean squares for reciprocal effects were non-significant for all the traits under study. Additive gene effects controlled the expression of the traits like flag leaf area, number of fertile tillers per plant and spike length as is evident by greater mean squares for general combining ability while non-additive type of gene action indicated the pre-dominant role for plant height and peduncle length. However it is concluded from the results that flag leaf area, number of fertile tillers per plant and spike length might be used as selection criteria for further breeding program.
