Abstract
Maize is one of the three leading cereals that feeds the world. Indeed, maize plays a versatile and dynamic role in food systems and food/nutrition security. Water deficit stress is considered as one of the most important environmental factors that adversely affects maize production. An ideal maize genotype should have a high average yield and a high a biotic stress tolerance. Considering the importance of maize production and the impact of water deficit stress on reducing the maize yield, estimating the genetic components and heritability of traits to choose the breeding method for hybrid production under water deficit stress is essential. The knowledge of gene effects for maize or any other crop is important to selection and breeding procedures for different characters. Many researchers revealed that importance of additive and non-additive effects in the inheritance of quantitative traits in maize. Generation mean analysis as the best biometrical technique, determine the genetic parameters including additive and dominant effects, and non-allelic genetic interactions using mean genotypic values of families and generations. To this end, we attempted to analyze the generation mean using seven basic generations of a cross between B73 and MO17 to explore how genes and trait interactions could lead to identifying better maize genotypes able to survive under water-deficitstress
