ABSTRACT
Eight inbred lines of maize were evaluated to determine the genetic mechanisms of leaf characteristics in maize inbred lines under different environments. The experimental material was planted under normal as well as water stress conditions. Data on yield and leaf characteristics revealed highly significant differences among inbred lines under both plantings. Graphical analysis revealed that additive gene action for soluble sugar content remained unchanged under water stress while over-dominance type of gene action for protein content, osmotic potential, stomata size and grain yield per plant under normal condition also remained unchanged under water stress whereas additive type of gene action for stomatal frequency under normal changed to over-dominance type of gene action under water stress.
