摘　　要：甘肃省高寒阴湿区豌豆镰刀菌根腐病的病原有5种,即茄病镰刀菌[Fusarium solani(Mart.)Sacc]、茄病镰刀菌蓝色变种(Fusarium sola-ni var.coeruleum)、半裸镰刀菌(Fusarium semitec-tum)、单隔镰刀菌(Fusarium dimerum)、拟丝孢镰刀菌(Fusarium trichothecioides)。茄病镰刀菌致病性最强,拟丝孢镰刀菌和茄病镰刀菌蓝色变种次之,半裸镰刀菌和单隔镰刀菌的致病性较弱。其中半裸镰刀菌、单隔镰刀菌、拟丝孢镰刀菌是中国豌豆病原菌上的新纪录。The pathogen of pea Fusarium root rot in the cold and humid regions of Gansu were Fusarium solani （ Mart. ） Sacc, Fusarium solani cioides. The most pathogenicity var. coeruleum, Fusarium semitectum, Fusarium dimerum and Fusarium trichothepathogen was F. solani, while F. trichothecioides, and F. solani varo coeruleum were the second;however F. semitectum and F. dimerum were the least pathogenicity pathogens. F. semitectum, F. dimerum,F, trichothecioides were new recorded on pea Fusarium root rot in China.
