| Abstract | ||||
| Soil salinity severely limits wheat production in Egypt and globally. This study evaluated twenty bread wheat genotypes from the Wheat Research Department breeding program under both non-saline and saline soil conditions during the 2021/2022 and 2022/2023 cropping seasons, in Nubaria, Egypt. The wheat genotypes were tested in an alpha lattice design to assess yield and yield components, physiological traits, and salinity tolerance. Measured traits included heading, plant height, days to maturity, flag leaf area, canopy temperature, stress tolerance indices, harvest index, biological yield, grain yield, and their components. The environments, genotypes, and genotype-by-environment interaction effects varied significantly for agronomic and physiological traits. The genotype + genotype-by-environment interaction effect (GGE) graphic identified line 1 and line 2 as superior under saline conditions, and line 7 performed best under non-saline conditions. Genotypes 9 and 11 were identified as stable and highly adapted across environments and were superior in genotype by salinity tolerance index (GSTI). Additionally, these genotypes demonstrated consistent yield and salinity tolerance and are recommended as promising candidates for cultivar release and use in a breeding program targeting saline calcareous soils. | ||||
