为了解决影响我省马铃薯生产的病毒病为害问题,近年来我们开展了马铃薯茎尖培养生产脱毒原种的研究(培养方法见本刊1980年第4期),已收显著成效。1978—1981年,我省共种植脱毒原种6,000多亩,生产脱毒原种900多万斤。经脱毒处理的种薯在田间未发现病毒病植株,植株长势好,表现增产。如克新3号和米拉品种的脱毒薯分别比对照增产161%和181%(图1和图
In order to solve the problem that affects the virus disease of potato production in our province, in recent years we have carried out the research on the production of virus-free seed by potato shoot tip culture (for the culture method see No. 4, 1980), and have achieved remarkable results. From 1978 to 1981, a total of 6,000 mu of detoxification seedlings were planted in the province, producing over 900,000 kilograms of detoxification seed. Virus-free seedlings in the field did not find virus disease plants, plants grow well, the performance of yield. The virus-free potatoes such as Kexin No. 3 and the Mira variety increased yield by 161% and 181% respectively as compared with the control (Fig. 1 and Fig.
