Abstract: Eighteen advanced Winter and intermediate cold hardy wheat genotypes and two advanced genotypes of Toos and Alvand as checks to compare their tolerance to the late season drought stress. The experiment was conducted under two different irrigation conditions of (a) normal irrigation and (b) late season drought stress condition where the last two irrigations were cut off after the heading of the wheat. Each of two experiments was conducted in a randomized complete block design with three replications and 20 wheat genotypes. The analysis of variance showed that genotypesxenvironmentsxregressions interaction and AMMI component 1 were significant. Results show that 10(5002), 2(4016), 15(5034), 1(4002) and 6(4034) the high seed yield in all of sites and all of environment conditions and two years (2007-2008). These genotypes had the high seed yield in normal and drought stress. The 10, 2, 15, 6, 7 and 11 genotypes have rather good adaptation to a wide range of environments toward other genotypes and selected for stabile genotypes.
