Abstract:

 This research was carried out during the Agronomic season 2021- 2022 in green house pot experiments in order to study the effect of two levels of water stress (55 and 75%) of field capacity in comparison to the control (100%) of field capacity on some morphological and productive traits of six genotypes of durum wheat. The results showed negative effect of water stress on all traits. The productivity decreased by 55.11% and 70.05% at level of water stress 75% and 55%, respectively. The results also showed that the most sensitive genotype to water stress was A.1431with an average grain yield of (459.1)g/m2, while the genotypes, Doma.1 and D.55756, were the most tolerant with an average grain yield of (600.8, 591) g/m2, respectively.
The simple linear correlation analysis showed a highly significant positive correlation between grain yield and both the number of grains/plant and the harvest index, which indicates the importance of these two traits in selection of grain yield in dry environment.
