Yield is economically most important and most complex polygenic trait. To meet the todays challenges new genotypes of wheat are being evaluated by continued genetic recombination. Efforts to improve wheat plant have been made at various plant characters. Yield component breeding and modification of the plant architecture offer possibilities to develop more efficient breeding systems for increased grain yield.Therefore, the present studies were designed the genetic behavior of some polygenic (Morpho-physiological) characters of spring wheat were brought under consideration in order to determine the Gene action involved in their inheritance. Information so derived would be efficiently exploited to design suitable strategies for sustained genetic improvement of this essential food crop.
