摘　　要：我国玉米生产中,由于品种高度同质化、多年连作、秸秆还田以及极端气候频发等因素,造成玉米病害流行,且呈逐年加重之势,严重威胁玉米的产量和品质。培育玉米抗病品种是防控病害的根本途径,而克隆玉米抗病基因并解析其作用机理则是培育玉米抗病品种的基础。近十年来,玉米抗病基因的定位克隆和机制研究进展迅速,相较前二十年取得了显著突破,极大促进了玉米抗病遗传研究和育种应用。综述了玉米抗病基因挖掘及其作用机制研究的最新进展,阐述其在育种应用上的潜在价值,以期加速玉米优良抗病新品种的培育。Due to factors such as a high degree of variety homogenization,multi-year continuous cropping,straw returning to the field,and frequent occurrence of extreme weather,diseases have become prevalent in maize production in China,with their incidence increasing year by year.This trend seriously threatens both the yield and quality of maize.Breeding maize disease-resistant varieties is the fundamental solution to controlling the diseases,while cloning maize disease-resistant genes and analysing their mechanism of action forms the foundation for such breeding efforts.Over the past decade,significant progress has been made in QTL mapping and gene cloning related to maize resistance,greatly benefiting research and applications in disease resistance breeding.The recent advances in the mining of maize disease-resistance genes and their mechanisms of action are reviewed,and their potential value in breeding applications is described,with the objective of accelerating the breeding of new maize varieties with excellent disease-resistance performance.
