Evaluation of genetic diversity of durum wheat (Triticum durum L. ) genotypes based on physiological and biochemical traits in non-tension conditions

In order to investigate the genetic diversity, 20 genotypes of durum wheat were evaluated in a randomized complete blocks design with three replications in a research farm of Agricultural Campus, Razi University of Kermanshah, for the grain yield, physiological traits and activity of antioxidants enzymes in 2013-14 cropping year. The results showed that there was a significant difference between the cultivars for all traits except leaf water content at the probability level of one percent. Heritability, genetic enhancement and high genetic variance for the traits of grain yield and saturated water deficit was observed. Therefore, selection of genotypes based on these traits has high efficiency. Level of enzyme activity of superoxide dismutase and catalase enzyme activity were positively and significantly correlated with water stored in cut leaves. Totally, among the investigated genotypes, there was a significant difference between all the investigated traits, which indicates the optimal efficiency of the genotypes studied for corrective purposes.
