To test the nature of gene action under normal and stress environments, four wheat (Triticum aestivum L. subsp. aestivum) varieties/lines were crossed in a diallel fashion. The graphic representation showed that traits like flag leaf area, number of fertile tillers per plant and spike length were controlled by partial dominance with additive gene action. While 100-grain weight and grain yield exhibited over-dominance type of gene action under irrigated conditions, under drought conditions the mode of gene action was changed in some traits. Flag-leaf area and spike length showed over-dominance type of gene action, whereas number of fertile tillers per plant, 100-grain weight and grain yield per plant exhibited partial dominance type of gene action
