e0“28 bread wheat genotypes (7 parents and their 21 hybrids) were evaluated in two separate experiments under water-deficit (two irrigations) and well-watered (five irrigations)”
e1“Water stress caused reductions in days to 50 % heading, plant height, spike length, number of kernels / spike, 1000-kernel weight and grain yield / plant traits by 5.19, 11.15, 16.39, 16.90, 10.67 and 8.98 % respectively”

- Intervention effect Water stress reduced days to 50 % heading by 5.19% relative to well-watered plants.
- Intervention effect Water stress reduced plant height by 11.15% relative to well-watered plants.
- Intervention effect Water stress reduced spike length by 16.39% relative to well-watered plants.
- Intervention effect Water stress reduced 1000-kernel weight by 10.67% relative to well-watered plants.
- Intervention effect Water stress reduced grain yield / plant by 8.98% relative to well-watered plants.
- Observation Parents Misr 2 and Line 117 were identified as suitable under water stress by low TOL and SSI values.
- Observation Crosses Sids14 x Sakha 95, Sids14 x Line 117 and Misr 2 x Line 136 were identified as suitable under water stress by low TOL and SSI values.
- Observation The genotypes identified as suitable expressed the highest yield under stress conditions.
- Observation Parental genotypes Sids 14 and Sakha 95 were identified as highly drought-tolerant.
- Observation Hybrids Sakha 95 x Misr 2 and Sakha 95 x line 115 were identified as highly drought-tolerant.
- Recommendation These genotypes could be used in wheat breeding to improve grain yield under water deficit.
- Observation Highly significant differences were detected among the tested genotypes for all the studied traits under normal and water stress.
- Observation Water-deficit stress declined the means of all the studied traits.
