马铃薯退化一直是影响马铃薯产量和品质的重要因素。研究表明,马铃薯退化主要是由于病毒侵染所致,只要脱去病毒,马铃薯产量就能大幅度提高。应用实生种子生产健康种薯,是一种简便而有效的脱毒方法,实生薯做种薯一般能增产25～50％,而且成本低,适合在云南广大山区推广应用。现将此技术介绍如下。一、选用良种马铃薯生产普遍是无性繁殖,应用实生种子后,变为有性繁殖,后代将出现分离, Potato degradation has been an important factor affecting potato yield and quality. Studies have shown that potato degradation is mainly due to virus infection, as long as the virus off, the potato yield can be greatly improved. It is a simple and effective detoxification method to produce healthy seed by using real seed. The seed potato made from real potato can generally increase yield by 25% ~ 50% with low cost and is suitable for popularization and application in vast mountainous areas of Yunnan. Now introduce this technology as follows. First, the selection of seed potato production is generally asexual reproduction, the application of seed after the seed, become sexual reproduction, offspring will appear separation,
