摘要: 玉米灰斑病是由尾孢属真菌引起的叶部病害, 在我国西南、东北等玉米主产区频繁发生, 严重影响我国玉米生产安全。玉米灰斑病抗性是由多基因控制的复杂数量性状, 易受环境影响。本文简要阐述了玉米灰斑病不同病原菌在我国南北玉米区呈地域性分布特征, 以及病原菌传播与侵染途径、发病条件与症状表现, 总结了化学防治策略、已鉴定的玉米抗性种质资源, 重点总结了玉米灰斑病抗性QTL位点的热点区域、抗性候选基因以及已克隆基因的抗病机制研究进展, 为深入研究玉米灰斑病抗性机制及培育抗灰斑病玉米品种提供理论依据。

Abstract: Gray leaf spot (GLS) of maize, caused by fungi of the genus Cercospora, is a foliar disease that occurs frequently in major maize-producing regions such as Southwest and Northeast China, severely threatening the safety of maize production Maize resistance to GLS is a complex quantitative trait controlled by multiple genes and is highly susceptible to environmental influences. This review briefly elaborates on the regional distribution characteristics of different GLS-causing pathogens in the northern and southern maize-growing regions of China, as well as the transmission and infection pathways of the pathogens, the conditions for disease occurrence, and symptom manifestations. It also summarizes chemical control strategies and the identified maize resistant germplasm resources. Emphasis is placed on summarizing the research progress regarding hotspots of GLS resistance quantitative trait locus (QTL) sites, resistance candidate genes, and the disease resistance mechanisms of cloned genes. This review provides a theoretical basis for in-depth research on the mechanisms of maize resistance to GLS and the breeding of GLS-resistant maize varieties.
