Wheat (Triticum aestivum L.) being the most valuable staple food is highly regarded in the world as king of cereals. Being an agriculture country, Pakistan's economy primarily depends on this sector and wheat no doubt is the mainstay of agriculture in our country. Among all wheat traits, yield is one of the most complex and economically important characters. Identification and improvement of superior genotypes can only be possible through exploiting latest plant breeding techniques.The evaluation of new genotypes by continued genetic recombination is the need of the day. In order to achieve the maximum genetic gain with minimum resourses and in minimum time, the gene action studies are of great importance in executing an efficient breeding programme, and attaining useful information regarding the selection of hybrids in terms of performance of their parents.The experiment was conducted to determine the gene action of different wheat genotypes for some morphological traits of high economic value like plant height, peduncle length, spike length, number of tillers per plant, number of spikelets per spike, flag leaf area, number of grains per spike, 100-grain weight.
