Evaluation of Terminal Drought Tolerance in Durum Wheat Genotypes by Using of Drought Tolerance Indices

In order to investigation of response of durum wheat genotypes to terminal drought stress, this experiment was conducted in Neishabour Agricultural Research Station during two growing seasons of 2004-2005 and 2005-2006. Seventeen advanced durum wheat genotypes, two bread wheat cultivars and one durum wheat cultivar (i.e. 20 genotypes and cultivars) were evaluated in two separate experiments (normal and limited irrigation) based on a randomized complete block design with four replications. Combined ANOVA of grain yield data revealed that there were significant differences among genotypes for grain yield of Durum Wheat (P)
