Abstract:\u00a0<\/strong><\/span><\/p>\n

The study was conducted at Kharhta Research Station, which belongs to the General Commission for Scientific Agricultural Researches (GCSAR), during the growing season 2017 \u2013 2018, to evaluate the response of ten bread wheat genotypes under water stress conditions throw the life stage of the plant by stopping irrigation compalatily. The experiment was laid according to the randomized complete block design (RCBD) with three replications for the control (without water stress) and water stress treatments both during anthesis and grain filling stages. Water stress conditions negatively affected in all studied quantitative traits, The response of the studied genotypes to stress varied according to the life stage of the plant exposed to water stress (flowering, grain fullness). The genotypes Bohooth8, Douma6 and Sham10 were more adaptable to water-limited conditions during the two studied developmental stages, maintaining significantly higher grain yield compared with the remaining investigated genotypes, which is attributed to their superiority in the grain related traits such as number of grains per spike, number of spikes per square meter and 1000-kernel weight, which can be considered as key traits to be selected for in the plant breeding programs to improve the production capacity of\u00a0 wheat under water deficit conditions.<\/span><\/p>\n

Key words:<\/strong> genotypes, water stress, bread wheat, grain yield.\u00a0\u00a0<\/span><\/p>\n
