Although drought stress has been well documented as an effective parameter in decreasing crop production in arid and semi arid regions. The objectives of this study were to detect the effect of irrigation on grain yield, yield components and other morphological traits of asset wheat genotypes. The present study was carried out to study the performance of durum wheat genotypes in relation to yield and yield component. Ten durum wheat (Triticum durum Desf.) cultivars were grown under well watered and natural drought conditions. Morphological traits were measured at anthesis and yield, yield components traits were evaluated at ripening time. The experiment was laid out in split plot based on a complete randomized block design, with four replications at the experimental field of ITGC Setif. The number of spike m-2, 1000-kernel weight, plant height, grain yield and peduncle length were highly significant (P<0.01) affected by water deficit conditions and genotype effects. Chlorophyll content, number of grains per meter square and thousand kernel weights were positively associated with grain yield under drought conditions. Moreover, the grain yield was negatively associated with Drought Susceptibility Index (DSI) (r = -0.64). DSI values for grain yield ranged from 0.42 to 1.38, values for grain yield ranged from 52.20 to 64.63 Qx/ha. The varieties Waha, Sooty, Dukem and Hoggar showed high yield (GY≥ 60 Qx/ha), among these genotypes Waha and Hoggar have low value of DSI (DSI< 0.55).
