　　对我国玉米主要病害发生现状及发生原因进行了分析，认为生产上玉米杂交种遗传基础狭窄、缺少多抗性品种、耕作栽培制度的改变以及气候条件的变化，是造成玉米病害发生的主要原因。阐述了玉米新品种选育过程中的病害控制，提出了玉米抗病性育种策略，即以培育多抗玉米品种为目标，加强种质的基础性研究；通过多种途径改良玉米抗病种质资源；加强玉米种质资源的抗病性鉴定工作。

The occurrence status and reasons of maize main diseases in our country were analyzed.It was found that the main reasons causing maize diseases in production were narrowness of genetic basis of maize hybrids , shortage of multi-resistance maize hybrids, changes of husbandry and cu1tivation practice, climate conditions.The disease control in process of breeding of new maize varieties was elaborated in the paper , and the breeding strategies for disease resistance was put forward including the development of maize hybrids with multi-resistance, strengthening basic research, enriching resistant germplasm resources, especially identification for disease resistance of maize germplasm resources.
