dc.description.abstractWheat stem rust, which is caused by Puccinia graminis f. sp. tritici ( Pgt ), is a highly destructive disease that affects wheat crops on a global scale. In this study, the reactions of 150 bread wheat varieties were evaluated for natural Pgt infection at the adult -plant stage in the 2019 - 2020 and 2020 - 2021 growing seasons, and they were analyzed using speci fi c molecular markers to detect stem rust resistance genes ( Sr22 , Sr24 , Sr25 , Sr26 , Sr31 , Sr38 , Sr50 , and Sr57 ). Based on phenotypic data, the majority of the varieties (62%) were resistant or moderately resistant to natural Pgt infection. According to molecular results, it was identi fi ed that Sr57 was present in 103 varieties, Sr50 in nine varieties, Sr25 in six varieties, and Sr22 , Sr31 , and Sr38 in one variety each. Additionally, their combinations Sr25 + Sr50 , Sr31 + Sr57 , Sr38 + Sr50 , and Sr38 + Sr57 were detected in these varieties. On the other hand, Sr24 and Sr26 were not identi fi ed. In addition, many varieties had low stem rust scores, including a large minority that lacked Sr57 . These varieties must have useful resistance to stem rust and could be the basis for selecting greater, possibly durable resistance.
