摘要：

27 Rhizoctonia solani isolates from carnation with damping-off symptoms were identified as anastomosis group AG-4 based on cultural characteristics and anastomosis in Yunnan.Sequence analysis of 5.8S rDNA-ITS of yx and tx presented 99% sequence similarity with AG-4 HGⅠtester isolate.Pathogenicity tests showed that isolates of AG-4 HG Ⅰ were pathogenic to carnation.This is the first record of damping-off of carnation caused by AG-4 HG Ⅰ in China.
