Molecular Description for Some Promising Wheat Accessions Tolerated to water Stress

Abstract

In light of the risks and challenges facing Egyptian national security, it was found that there are two strategic crises that dominate the Egyptian scene, namely the limited irrigation water and the large deficit in Egyptian bread production. Also, it is noted that the wheat crop is very sensitive to drought stress, especially in the valley and delta regions and areas close to the sea coast. This large deficit in
irrigation water causes great damage to the final yield which amounts to 50%. Since, the wheat crop represents the backbone of Egyptian bread production, bread production is severely damaged and affects the vast majority of Egyptians. For all these reasons combined, this investigation was launched with the aim of attempting to genetically improve some wheat entries that are sensitive to drought and raise their tolerance to it besides, reach wheat hybrids that are superior in yield and water stress tolerance so that these entries become new wheat lines in the future. Further, these wheat lines can participate significantly in bridging the large gap in the production of Egyptian bread.
