Abstract

This study was conducted to estimate COMBINING ABILITY, GENE ACTION and PROPORTIONAL CONTRIBUTION of cross components in some MAIZE genotypes under different irrigation conditions. In 2007 in Research Farm of Islamic Azad University, fifteen MAIZE inbred lines as parents, consist of twelve females (No: 4-15) and three males (NO: 1-3) were crossed to produce 36 F1 hybrids. Parents and their 36 F1 hybrids were evaluated in a RCB design with three replications under irrigation after 70, 90 and 110 mm evaporation from a class A pan in 2008. Results showed both additive and dominance variances were important under DROUGHT STRESS conditions. Gene expression increased with intensify of DROUGHT STRESS. PROPORTIONAL CONTRIBUTION of lines, testers and their interactions revealed that female line contributed higher compared to male line under DROUGHT STRESS conditions in all studied traits and maternal parents play the most important role under DROUGHT STRESS conditions. The ratio of GCA to SCA variances was less than unity for all studied traits and showed the predominant role of non additive action in the inheritance. In conclusion, it can be suggested that female parents should be considered more for a successful plant breeding programs under DROUGHT STRESS conditions.
