Abstract
Twenty one bread wheat genotypes introduced from ICARDA along with the Egyptian check (Sakha 61) were evaluated for tolerance to water stress in two sucessive seasons (199912000 and 200012001). Three moisture levels were used; 100% (control), 70% and 50% of field capacity. Water stress treatments resulted in significant reductions in growth parameters, nutrient uptake, chlorophyll and yield components, while proline content increased for all genotypes. Root length, leaf area, proline, chlorophyll, NPK, sugar and amino acids were good criteria for drought tolerance and they were highly correlated with yield components. Five genotypes exhibited high dry matter accumulation, proline concentration and better yield parameters under water stress conditions and were either equal to or better than the Sakha 61. Two of the source parents (Kauz's' and Vee's') were common in the tolerant genotypes and are potentially a good source for water stress tolerance in wheat breeding programs.
