Evaluation of Durum Wheat Lines Tolerance to Salinity and Drought Stress under Greenhouse Conditions

Abstract

This research was carried to evaluate seven durum wheat lines to salinity and drought stress under greenhouse condition at the Faculty of agriculture, Islamic Azad University, Tabriz Branch in using a factorial experiment based on randomized complete block design with three replications and three factors. These three factors were salinity stress with two levels (non stress and stress with 6.2 ds), drought stress with two levels (non stress and stress with FC %50) and seven durum wheat lines. According to the results of analysis of variance significant differences were observed among investigated lines for the most of the traits. Mean comparison indicated that ARAMIDIS and Yazligh lines exhibited the highest value for the majority traits. Grain yield had positive and significant correlation with the most of the traits. Cluster analysis, based on Ward method, grouped two lines of ARAMIDIS and Yazligh in to the separate and superior groups. However the two lines ARAMIDIS and Yazlig were identified to be resistant to both salinity and drought stress conditions.
