“…Furthermore, moisture stress during grain filling may limit photosynthates delivery from leaves to spike, hence decreasing seed size. Bashir et al, (2017); Si et al,(2020) and Khan et al, (2022) reported that decreasing number of irrigations and amount of water decreased wheat grain yield at the different growth stages. Low grain yield under water stress was mainly due to the obvious reduction in the yield components such as spikes number, kernels number and 1000-kernel weight during the critical growth stages.…”

Water scarcity is one of the most significant constraints to wheat production in Egypt and around the world. Therefore, twenty genotypes and four cultivars of bread wheat were tested under normal irrigation (six irrigations including planting irrigation) and water deficit stress (two irrigations at 21 and 45 days after the planting irrigation) during the 2020/2021 and 2021/2022 growing seasons at Shandaweel Agricultural Research Station, Sohag, Egypt. Each irrigation treatment was considered a separate experiment in the randomized complete block design. The two seasons and two water treatments showed sufficient genetic variability among the studied genotypes. The number of days to heading and maturity, plant height, yield and its components traits significantly decreased under water deficit stress. The genotypes G13 and G17 significantly outperformed all studied genotypes and checked cultivars for grain yield under normal irrigation and water stress conditions. The genotypes G16, G2, G12, G9, G17, G20, G18, G8, G10 and G5 as well as cultivars Sids 14, Sokoll and Kasuko showed stress susceptibility index (SSI) <1 and they can be used as a source of water deficit tolerance in a breeding program. Genotypic main effect plus genotype by environment interaction (GGE) Biplot analysis revealed that the genotypes G13 and G17 had high yielding ability but genotype G17 showed more stability and tolerance under water stress conditions. Therefore this study concluded that the genotypes G13 and G17 were suitable genotypes to be cultivated under water shortage conditions and could be used to enhance the wheat breeding program for water deficit stress tolerance.

“…These findings emphasize the importance of proper irrigation management and the selection of appropriate wheat cultivars to optimize grain yield in water-limited conditions. Bashir etal., [21] and Khan et al, [22] reported that decreasing the number of irrigations and amount of water decreased wheat grain yield at the different growth stages. The performance variations of wheat genotypes have been studied by various authors, specifically focusing on the number of grains per spike [2,8,[22][23][24][25][26][27].…”

The previous discussions regarding the yield components have revealed a consistent trend that is also observed in the case of the cultivar Misr-3.…”

and 2020/2021 growing seasons. The objective of the study was to assess the yield of newly developed bread wheat cultivars under conditions of water stress (drought indices). The experimental design was a split-plot in randomized complete block design with three replicates. The experiment consisted of two factors, which were three different water stress conditions and five different wheat cultivars. The results showed that skipping irrigations had a significant effect on grain yield, with the highest reduction of 42.9% observed when irrigations at the heading stage were skipped compared to full irrigation. The cultivar Sakha-95, Misr-3, exhibits a higher level of drought tolerance during the elongation and flowering stages. Stress susceptibility index (SSI) under drought stress conditions (skipping irrigation during the elongation stage and skipping irrigation during heading stages), the Sakha-95 performed better in the two irrigation skips on grain yield. Misr-3," followed by Sakha-95," are the top-performing cultivars in the yield index (YI) of drought tolerance during the flowering stages. Also, the Sakha-95" cultivar showed the highest stress tolerance index (STI) value of 1.08 when irrigation skips at the heading stage. While the cultivar "Sids-14" displayed the highest STI value (1.04), only irrigation at the elongation stage was skipped. The recommended of this study, Misr-3 is the most drought-tolerant cultivar, while Giza-171 is least tolerant. These traits highlight their resilience in water scarcity.
