In this research yield and yield components of 13 advanced winter and intermediate wheat genotypes obtained from the cold hardy wheat breeding stations of the country with two advanced genotypes as control were investigated under normal irrigation and after anthesis drought stress condition in a randomized complete block design experiment with three replications in Ardabil, Iran in 2006-2007. Combined analysis variance indicated that there were significant differences among the genotypes in their grain yield, 1000 grain weight, peduncle length, plant height, number and weight grain per spike and harvest index. Genotype SG-U7067 produced the highest yield under both normal irrigation and drought stress conditions. The yield reduction of this genotype was lowest under the drought stress conditions. Under normal irrigation no significant correlation was observed between the grain yield and other morphological characters, but under the drought stress conditions there were positive highly significant correlations between the grain yield and the 1000 grain weight and number of tillers per plant. Under both conditions there were a positive significant correlation between the number of tillers per plant and number of fertile tillers per plant.
