玉米矮花叶病预防性育种和抗病遗传研究标准化问题的商榷

在简要分析造成当前我国玉米抗病育种被动局面与短期行为的思想及问题的基础上，从理论和实践两方面的可行性出发，提出下一步玉米抗病遗传育种，应树立以防为主，防治结合的思想，开展与当前进行的生产上发生的主要病害抗病育种相结合的预防性育种工作及抗病遗传研究，并建立玉米对矮花叶病抗病遗传研究方法的标准化体系，该体系包括采用株系的依据、调查的性状和标准、亲本的要求及遗传模型和分析方法等。

Prophylactic Breeding and System Standardized Study on Inheritance of Resistance to Maize Dwarf Mosaic Virus

The important thing in maize resistant breeding is curing breeding for major diseases but not prophylactic breeding for the subsidiary diseases that will becoming more and more serious in China.It would be avoided that maize disease take place one after another by developing prophylactic breeding connected with curing breeding instead of only by curing breeding developed in maize resistant breeding.The standardization system of genetic study on resistance of maize dwarf mosaic virus including resistant index system,the strains of maize dwarf mosaic virus,the parent,and genetic models was beeing set up for the influences reduced by host,pathogen and environment.
