چکیده :

Wheat (Triticum aestivum L.) is one of the most important cereal crops globally, and increasing its production under water-limited conditions is of significant importance. This study aimed to investigate the effect of end-of-the-season drought stress on grain yield and protein percentage in different wheat genotypes. The experiment was conducted as a factorial design in a completely randomized block layout with two treatments: drought stress and non-stress, each with two replications. The results indicated that drought stress had a significant negative effect on both grain yield and protein percentage. The highest grain yield in non-stress conditions was observed in genotype 1622, while the lowest yield was recorded for the commercial cultivar Falat. Under drought conditions, genotype 1622 also showed the highest grain yield. Moreover, the highest grain protein percentage under drought stress was observed in genotype 1528. These results highlight the genetic variation in wheat genotypes responses to drought stress and the importance of selecting drought-resistant genotypes with high yield potential and suitable protein content. Overall, selecting drought-resistant genotypes with high performance and optimal grain quality can be an effective strategy to improve wheat production under water stress conditions.
