Abstract

Wheat stem rust caused by the fungus Puccinia graminis f. sp. tritici is one of the most destructive diseases. Here, we collected 43 stem rust isolates from six provinces of Iran during 2020–2022 and assessed variability in their virulence on 20 North American differential lines carrying one of the stem rust resistance genes. More than 90% of isolates were virulent on lines with gene Sr5, Sr9d, Sr9g, Sr30, Sr36, Sr38, SrTmp and SrMcN and the least virulent on those with Sr31 (16.2%) and Sr24 (0%). The majority of isolates belonged to races TKTTF, TTTTF, and TTTTK. Races TTTTK, TKTTK and PTTTK are new in Iran.

利用差异株系对伊朗小麦茎锈病分离株（禾谷镰孢属三尖杉菌）进行毒力分析

小麦茎锈病由真菌 Puccinia graminis f. sp. tritici 引起，是最具破坏性的病害之一。在此，我们于 2020-2022 年期间从伊朗 6 个省收集了 43 个茎锈病分离株，并评估了它们对 20 个携带一种茎锈病抗性基因的北美差异品系的毒力差异。超过 90% 的分离株对带有 Sr5、Sr9d、Sr9g、Sr30、Sr36、Sr38、SrTmp 和 SrMcN 基因的品系具有毒力，而对带有 Sr31（16.2%）和 Sr24（0%）基因的品系毒力最低。大多数分离物属于 TKTTF、TTTTF 和 TTTTK 型。TTTTK、TKTTK 和 PTTTK 是伊朗的新菌种。
