Rhizoctonia solani is a species complex which has been classified into 14 anastomosis groups(AG1-AG13 and AG-BI).*** AG-3,the causal agent of black scurf in potatoes,is an important potato pathogen causing significant yield and quality losses in potato *** this study,six potato black scurf strains were isolated form the diseased potato tissues in Gansu potato producing *** six strains were identified as AG-3 preliminarily according to the results of morphological analysis and hyphal anastomosis *** addition,two pairs of primers were designed based on the specific sequences of AG-3,which were used to amplify the genomic DNA of the six strains,*** results indicated that the six strains were *** detection has time saving advantages over traditional isolation methods for detection of *** on infected plant tissue and provides a powerful tool of identification.
