摘      要：Several fungal pathogens cause root rot of common bean,among which Fusarium *** the most common pathogens causing Fusarium root rot(FRR)*** has been becoming an increasingly severe disease of common bean in China,but the species of Fusarium *** remained ***,this study was performed to identify the pathogen causing common bean root rot in Liangcheng County,Inner Mongolia,*** Fusarium-like isolates were obtained after pathogen isolation and *** pathogenicity test indicated that eight isolates caused severe disease symptoms on common bean,while 11 other isolates were not *** eight pathogenic isolates,FCL1–FCL8,were identified as Fusarium cuneirostrum by morphological characterization and phylogenetic analysis using partial sequences of EF-1α,ITS,28S,and IGS *** range test showed that the representative *** isolate FCL3 was also pathogenic to mung bean,while not pathogenic to adzuki bean,chickpea,cowpea,faba bean,pea,and ***,50 common bean and 50 mung bean cultivars were screened for resistance to FRR,and seven highly resistant or resistant cultivars of common bean were identified,while no resistant cultivars of mung bean were *** study revealed that *** was one of common bean FRR pathogens in Inner Mongolia and it could induce mung bean root rot as *** our knowledge,this is the first report of *** causing FRR of common bean in China.
