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、东北等玉米主产区发病严重,严重威胁我国粮食安全。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。本文简要介绍玉米灰斑病在我国分布情况、传播途径、化学防治方法,重点总结了玉米灰斑病抗性QTL位点、抗性基因以及抗病机制研究现状,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 Cercospora fungi, is a severe foliar disease prevalent in major maize-producing regions of China, such as the southwest and northeast, posing a significant threat to the nation's food security. Maize resistance to GLS is a complex quantitative trait, controlled by multiple genes and highly susceptible to environmental influences. This paper briefly introduces the distribution, transmission pathways, and chemical control strategies for GLS in China, with a primary focus on summarizing the current research status concerning quantitative trait loci (QTL), resistance genes, and underlying resistance mechanisms associated with this disease. The aim is to provide a theoretical foundation for in-depth investigations into the resistance mechanisms of maize GLS and to facilitate the breeding of GLS-resistant maize varieties.
