Abstract:

 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).
