An experiment was conducted in the form of randomized complete blocks design as split plots with three replicates in both stressed and non-stressed conditions as the main plots by 12 durum wheat cultivars in the form of sub-plots on varieties including Fadda, Yavarus, Altar, Omrabi5, Zardak, Stork, Vadalmez, Omrabi6, Hurani, Korifera, Chakhmaq and Ammar, in this study grain and biomass yield, Superoxide Dismutase (SOD), Catalase (CAT), Ascorbat per oxidase (APO), Injury index (Id), Relative water content (RWC) were assessed in two stress and normal conditions were analyzed for variance, the results of split-plot analysis showed that the treatments in traits grain yield and biomass per hectare and Injury index were meaningful in probability level of 1%, the traits were analyzed for correlation and it was revealed significant correlation at 1% level between biomass and grain yield in water stress conditions, considering the results of split-plot variance analysis and mean comparisons, it was concluded that the antioxidant parameters can be used as an indirect selection criterion for screening drought-resistant of germ plasmas.
