Anastomosis group and pathogenicity of Rhizoctonia solani associated with ste…

Three hundred and fifty six isolates of Rhizoctonia solani were obtained from potato stems and tubers in the main potato growing regions of China between 2011 and 2014. On the basis of the hyphal anastomosis and sequence analysis of the internal transcribed spacers of the ribosomal DNA, 249 isolates (69.94 %) were identified to anastomosis group (AG)-3 PT, 44 (12.36 %) to AG-5, 39 (10.96 %) to …
