[Objective]To isolate and identify the pathogen causing potato black scurf in Xinjiang in the hope of providing a foundation for screening of control agents and establishment of control technology.[Meth-ods]Potato tubers were collected from Jimsar,Qitai,Dabancheng and Zhaosu in Xinjiang,and Rhizoctonia solaniwere isolated from tubers with potato black scurf by tissue separation method.Anastomosis groups of Rhi-zoctonia solaniwere identified by paired culture and ITS sequence analysis.[Results]The four strains isolated from Jimsar,Qitai,Dabancheng and Zhaosu were all able to cause the symptoms of potato black scurf on pota-to tubers.The isolated strains were Anastomosis groups AG3.[Conclusion]Anastomosis Groups AG3 is the main pathogenic group of potato black scurf in Xinjiang.
