摘　　要：玉米灰斑病是由玉蜀黍尾孢菌(Cecrosporazeae-maydisTehon&Daniels)引起的一种病害,最早于1924年在美国亚历山大州和伊利诺斯州发现,该病现在美国普遍发生。我国陈刚于1991年在辽宁省发现该病,至今该病在辽宁、吉林、河北等地均有发生熏并已对玉米生产造成了很大的威胁。从症状、病原、流行规律、发病条件、抗源鉴定、抗性机制、抗性遗传以及防治技术等方面对该病进行了综述,同时探讨了今后玉米灰斑病的研究方向和重点。Gray Leaf Spot（GLS） of Maize, caused by the fungus Cecrospora zeae-maydis Tehon ＆ Daniels, was first observed in Alexander state and Illinois state in 1924. It takes place in the United States now. In China Chen Gang first found this disease in Liaoning in 1991 and the disease was also founded in Jilin,Hebei and other provinces now. It has become a major threat to maize production in maize-growing regions. This paper reviewed the disease by symptom, pathogen, epidemic, inducing condition, identification of resistance, machanism of resistance,inheritance of resistance and control techniques, and discussed the disease research orientations.
