Abstract
One of the most important strategies of wheat modification in Mediterranean area is producing irrigated wheat genotypes which latently are able to give satisfactory yield in front of end-draught stress. In cold areas of Iran irrigated wheat is dealing with end-draught stress and evaluating genetic differences of its varieties and lines is an important issue. This experiment was conducted in order to determine the genetic differences of 30 bread wheat genotypes dealing with end-draught stress condition in the research farm of Islamic Azad University of Ardabil Branch the results of the research represented that tiller number, spike weight and plant height had higher genetic variation coefficients in comparison to the other traits. The number of spikes per square meter had high genetic output, and had high genetic variation too, and also had a suitable heritability. And plant height and number of days to ripening had maximum genetic output.
