Abstract

To study drought tolerance in INBRED LINEs is an important task in development of MAIZE hybrids with acceptable yield in moisture limited conditions. Twenty MAIZE INBRED LINEs were evaluated in three moisture conditions, normal irrigation, moisture stress in vegetative and reproductive stages, in three separate experiments, using randomized compelet block design with three replications, in experimental field of Seed and Plant Improvement Institute, Karaj, Iran in 2005 cropping season. Results using TOL and SSI indexes revealed that K3651/1 and K3615/1, as tolerant INBRED LINEs under stress conditions in reprodutive and vegetative stages respectively. These two indexes identify genotypes with low yield under normal and high yield under stress conditions. The higher value of MP, STI, GMP and Harm indexes indicate the tolerance of genotypes under consideration. K3615/2 (with 4.770, 2.700 and 2.430 t/ha) and k19/1 (with 4.200, 2.830 and 2.510 t/ha) under normal, stress conditions in vegetative and reproductive revealed as the high yielding lines underthree moisture conditions.
