１ 前 言 利用茎尖脱毒技术生产无病毒种薯，是２０世纪５０年代中期以后马铃薯种薯生产上的一大贡献。我国从７０年代就引进了该项技术，目前已在部分省市推广应用，脱毒种薯的增产效果非常明显，达３０％－５０％。现将马铃薯脱毒繁育及脱毒种薯的快繁技术介绍如下。２ 通过 1 Introduction The production of virus-free seed potatoes by the technology of stem-tip detoxification is a major contribution to the potato seed production since the mid-1950s. China introduced the technology from the 1970s, which has been popularized and applied in some provinces and cities. The yield-increasing effect of virus-free seed potato is very obvious, reaching 30% -50%. Now potato virus-free breeding and virus-free seed propagation techniques described below. 2 passed
