近年来,随着茎尖脱毒技术在生产上的应用,为防治马铃薯病毒性退化开辟了新的途径,使马铃薯产量获得了大幅度地提高。但是,目前在供种环节上普遍存在着原种繁殖世代长的问题,其根本原因是没有好的繁殖方法。原原种数量少,繁殖速度慢,满足不了生产单位的用种,严重影响脱毒薯的推 In recent years, with the application of the technique of tip detoxification in production, it has opened up new avenues for preventing and controlling potato virus degeneration and has greatly increased the yield of potato.
