我想就抗病育种和病菌变异问题谈一谈这方面的科技动态和水平。并对进一步开展枯萎病的抗病选种和生理型研究谈一点意见,供同志们参考,请批评指正。现分以下几个问题。(1)抗病品种在生产上的作用,(2)植物抗病性和它的遗传规律,(3)病原菌的变异,(4)抗病育种的方法。一、抗病品种在生产中的作用用抗病品种防治植物病害是简单易行的有效方法,特别是大田作物病害和土壤中病害一般用药剂防治效果不好,也不经济。对这类病害来说,采用抗病品种是唯一有效的措施。我
I would like to talk about the scientific and technological developments and the level of disease resistance breeding and germ variation. And to further carry out the disease resistance of blight selection and physiological type of talk about some ideas for comrades for reference, please criticism and correction. Here are a few questions. (1) the role of resistant varieties in production, (2) plant disease resistance and its genetic law, (3) variation in pathogens, and (4) methods for disease resistance breeding. First, the role of disease-resistant varieties in the production of disease-resistant varieties of plant diseases prevention and control is an easy and effective method of simple, especially crop diseases and soil diseases in the general use of the agent control effect is not good, not economical. For such diseases, the use of resistant varieties is the only effective measure. I
