摘　　要：在辽宁丹东新发现一种软枣猕猴桃根腐病害,罹病植株叶片枯萎,老叶变干凋谢,最后干枯死亡。通过组织分离法和单孢分离法获得纯化菌株HMQAU150043和HMQAU150044。经形态学观察、ef‐1a序列分析、mt SSU序列分析及柯赫氏法则验证,确定两株病原菌均为多见镰孢Fusarium commune。这是该菌所致软枣猕猴桃根腐病的首次发现。A new disease was found on Actinidia arguta with symptom of root rot in Dandong, Liaoning Province. The diseased plants initially showed wilting, withering and falling of the older leaves until plant death. A procedure of tissue isolation and single spore culture was carried out to generate the isolates HMQAU150043 and HMQAU150044. According to morphological characteristics and e f-la and mtSSU sequence analyses together with pathogenicity test, the pathogen was identified as Fusarium commune. The species is firstly reported as the pathogen of bower kiwifruit root rot.
