种薯退化严重地影响着马铃薯产量的提高和播种面积的扩大。解放后,特别是无产阶级文化大革命以来,我国马铃薯栽培地区的广大贫下中农和科技工作者因地制宜的研究和总结出许多有效的防止退化的办法,取得了一定的成绩。为了使马铃薯的生产能稳定的获得优质种薯,建立原种生产基地是非常必要的,它是马铃薯生产上的一项基本建设,是使其它措施更能发挥效果的保证。下面就马铃薯病毒与退化和原种生产中的几个问题作一个简单介绍。马铃薯病毒与退化的关系为了弄清病毒、高温与马铃薯退化的相互关系,我们曾利用男爵品种天然实生苗的单株无毒种薯,在严格杜绝防止病毒感染的条件下,分析了病毒和高温两 Degradation of potato seriously affects the increase of potato yield and the expansion of sown area. Since the liberation, especially after the Great Proletarian Cultural Revolution, the majority of poor and middle-income middle peasants and scientists in the areas where potato cultivation in our country have studied and summed up many effective ways to prevent degeneration and have achieved some success. In order to ensure the stable production of high-quality potato seed production, the establishment of seed production base is very necessary, it is a potato production of a basic construction, is to make other measures to ensure that more effective. The following is a brief introduction of potato virus and the degradation and the production of several kinds of problems. Relationship between Potato Virus and Degeneration In order to understand the relationship between virus, high temperature and potato degeneration, we have used the nontoxic seedlings of Baron’s natural seedlings to strictly prevent the virus from infecting, and analyzed the relationship between virus and high temperature Two
