AB  - Salinity poses a danger to food security; hence, it is necessary to create crop types that can withstand salt to meet the growing demand for food. The goal of the current study was to examine the morphological and biochemical responses of wheat (Triticum aestivum L.) genotypes under salt stress. Salt tolerance in ten wheat cultivars and five selected F1 hybrids was assessed at the germination and seedling stage. Genotypes were assessed for seven traits under control (0 mM NaCl) and salinity stress (150, 200, and 250 mM NaCl). According to the findings, salt stress significantly impacted every wheat genotype. However, according to the STI value at 250 mM NaCl stress, Kharchia-65 was the most tolerant cultivar among the tested ones, followed by Pasban-90 and Krl-1-4. Also, Misr-3 is a promising Egyptian cultivar with moderate susceptibility. H5 (Pasban-90 × Kharachia-65) recorded the highest STI value among the tested hybrids. SDS-PAGE showed the appearance of some new bands under salinity conditions (200 and 250 mM NaCl). Protein bands with molecular weights 37.5, 40, and 48.6 kDa appeared in salt-treated cultivars at both concentrations. The current study’s findings may aid in developing salinity-tolerant wheat varieties. Ultimately, Kharachia-65 and H5 (Pasban-90 × Kharachia-65) recorded higher tolerance to salt stress. This data can be used in wheat breeding programs for salt-affected areas.
