大麦根腐病是严重危害大麦产量和品质的世界性病害之一，在我国的大兴安岭西麓和长江流域分布广泛。大麦根腐病是由根腐离蠕孢菌（ Biplaris sorokiniana）引起的真菌性病害，其致病菌可寄生也可腐生，适应性极强。本文主要从大麦根腐病的病原及其生物学特性、寄主范围、病害症状、病害鉴定、抗性遗传和防治方法等方面进行了综述，并展望了大麦根腐病的研究前景。

As one of the most serious worldwide disease affecting the yield and quality of barley,Root Rot Disease was widely distribu-ted in the Daxinganling mountain area and the Yangtze River basin in China. Root Rot Disease in Barely is the fungal disease caused by Biplaris sorokiniana and its pathogenic bacteria can be parasitized and also can be saprophyticed with strong adaptability. This paper mainly reviewed the cause of root rot disease,its biological characteristics,host range,disease symptoms,identification of the disea-ses,genetics of resistance,and measures on how to control this disease as well as the outlook of the research prospects in root rot dis-ease in barley.
