چکیده

This study was conducted to evaluate the effect of planting date on damage inflicted on the charactersAssociated with a cluster of wheat stripe rust pathogen of wheat affected by weather conditions in the Northern Province crop year 90-1389 a split plot randomized complete block design with three replications. In this experiment, the planting date (ninth and tenth) as main plots and cultivars as sub plots were examined. The results showed that delayed planting trait because of early exposure toThe growth period of winter rainfall as one of the most important factors in the developmentThis condition leads to an increase of 25% plants were infected with this disease. All traits were reduced to non-grain weight and grain number per panicle hollow other traits (yield, grains per panicle and panicle length), this reduction was significant. Chamran cultivars in the first planting on average 3733.3 kg ha grain yield respectively. It is hoped with resistant cultivars in order to manage them properly, especially at the beginning of autumn rainfall is an effective step in controlling and reducing the damage to be removed
