This experiment was conducted in order to identify tolerant genotypes to drought and evaluation of main characters and drought resistance indices on 20 bread wheat genotypes (18 promising lines and 2 checks, Sardari and Azar-2) during three cropping seasons (2002-2005) in two locations, Kermanshah province, Sararood station (moderate cold area) and Maragheh, Maragheh station (cold area). The genotypes were evaluated in a RCBD design fashion with four replications. Simple and combined analyses of variance for three years were carried out. The results showed significant differences among genotypes in different irrigation application. The highest grain yield, yield stability, and drought tolerance were belonged to the genotypes nos.
