This study aimed to assess the NaCl tolerance of 10 bread wheat (Triticum aestivum L.) cultivars during germination and early seedling development. The evaluation was conducted on shoot dry weight and shoot length across five salt concentrations (0, 4, 8, 12, and 16 dS m⁻¹).The effects of salt treatment, variety, and the interaction between salt and variety were statistically significant (P<0.01, P<0.05) for all examined wheat varieties (Serince, Hamza, NKÜ Lider, Almeria, Adana99, Bora, Eksperia, Falado, Selimiye, Gelibolu). Regression analysis and GGE biplot analysis were conducted to assess varieties under various salt treatments, treating the salt treatments as "environments." The GGE biplot accounted for 97% of the overall variation. The relative positions of variety in the regression graphs and GGE biplot graphs were congruent. The varieties NKÜ Lider, Serince, Bora, and Almeria had a lesser reduce in weight under salt stress compared to the control and demonstrated positive PC1 and PC2 values, thus being recognized as the most salt-tolerant. Conversely, the cultivars Adana99, Selimiye, and Gelibolu, which exhibited low shoot dry weight under control conditions and were significantly impacted by salt treatments, were identified as the most salt-sensitive. The GGE biplot approach determined 8 dS m⁻¹ as the threshold for salt tolerance based on the average axis utilized for variety selection. The paper indicates that integrating regression analysis with GGE biplot analysis in future investigations of salt-tolerant genotypes will enhance selection efficacy for researchers.
