摘　　要：玉米穗腐病不仅会使玉米减产,而且会降低玉米籽粒品质,给玉米生产带来重大影响。为了加深对玉米穗腐病的了解,本文从病原菌种类、侵染途径、发病症状、主要真菌毒素及危害、抗源鉴定和抗病遗传机制解析等方面进行了总结,同时简单介绍了基因编辑技术在抗性育种上的应用,并对玉米穗腐病的抗病育种进行展望,为玉米穗腐病抗病种质资源的创制及抗病新品种的培育提供理论参考。Maize ear rot not only reduces maize yield,but also decreases grain quality,which has a great impact on maize production.In order to deepen the understanding of ear rot of maize,this paper summarized the types of pathogenic bacteria,infection routes,symptoms,main mycotoxins and hazards,resistance source identification and analysis of resistance genetic mechanism,and briefly introduced the application of gene editing technology in resistance breeding,and prospected the resistance breeding of ear rot of maize.It provides a theoretical reference for the development of maize ear rot resistant seed resources and the cultivation of resistant new varieties.
