摘要: 目的】实地调查分析新疆伊犁地区新源县田间小麦条锈病和野外小檗锈病发生情况,为揭示新疆小麦条锈菌的群体遗传多样性以及小檗在小麦条锈病发生流行中的作用提供基础数据。【方法】利用中国小麦条锈病菌鉴别寄主,对2013~2015年新源县小麦条锈菌进行生理小种鉴定,对异果小檗种类鉴定、锈孢子DNA提取及PCR检测。【结果】新源县小麦条锈菌主要类群有Hybrid46类群,出现频率高达31.25%;水源11类群出现频率为22.92%;贵农22类群出现频率为18.75%;中四类群出现频率为6.25%;其他类群出现频率为20.83%。异果小檗锈病鉴定结果表明,异果小檗锈病中存在小麦条锈病,条锈菌锈子器的检出率在4.7%~5.7%。【结论】新源县小麦条锈菌主要为Hybrid46类群、水源11类群、贵农22类群。异果小檗锈病中存在小麦条锈病,条锈菌锈子器的检出率在4.7%~5.7%。

Abstract: Objective】 The purpose of this project is to investigate the rust-infected Berberisheteropoda Schneid in spring wheat in order to accumulate data on the genetic diversity and virulence variation of Puccinia striiformis f. sp. tritici (Pst) population in Xinyuan of Xinjiang and the control of wheat stripe rust in China in the future.【Method】The race analysis was carried out with Chinese differentials for Pst from Xinyuan populations in 2013-2015. We also identified the species of B. heteropoda Schneid, extracted the DNA from aeciospores and PCR reactions were amplified.【Result】In Xinyuan, the main pathotypes were Hybrid46 group at a rate of 31.25%, Suwon 11 group at a rate of 22.92%, Guinong 22 group at a rate of 18.75%, Zhong 4 group at a rate of 6.25% and unclassified group at a rate of 20.83%. Aecia on B. heteropoda Schneid were identified at a rate of 4.7%-5.7% by PCR detection with specific molecular marker of Pst.【Conclusion】The pathotypes of Xinyuan populations consisted of Hybrid 46 group, Suwon 11 group, Guinong 22 group and other undesignated races. Aecia of Pst on B. heteropoda Schneid was identified at a rate of 4.7%-5.7% by PCR amplifications with molecular marker specific to Pst.

Key words: wheat stripe rust; B. heteropoda Schneid; molecular detection; race
