The RAPD was used to study the genetic diversity of 19 KinXin series potato cultivars. The result showed that 52 RAPD bands were amplified using 7 primer, among them 43 bands were polymorphic, and 4~9 bands were amplified in each lane. The RAPD analysis indicated that the genetic distance of 19 potato cultivars was between 0.17~0.72, average value was 0.39. When all of the polymorphic bands were analysed by cluster analysis, 19 potato cultivars were classified into 3 groups. The analysis showed that there existed close sibship among the majority of potato cultivars, and the genetic distance between the minority cultivars and the others is longer, which indicate that the genetic basis of KeXin series potato cultivars is wide.

利用RAPD标记技术对19份克新系列马铃薯品种进行了遗传多样性分析，分别提取19份马铃薯品种的DNA，进行随机引物多态性扩增，从1000条随机引物中初步筛选出7条有多态性的引物进行详细研究，每条RAPD引物扩增出4~9条带，共获得52条带，其中多态性条带为43条；19份马铃薯品种的遗传距离介于0.17~0.72之间，平均值为0.39，平均遗传距离介于0.31~0.51之间；聚类分析结果在GS=0.53处可将克新系列马铃薯品种划分为三类，聚类结果与系谱分析基本相符，同时也说明克新系列马铃薯的遗传基础有所拓宽。

In screens 20 from 100 10bp along with the machine-drawn to increase the effect to direct the thing well to carry on increases, altogether has 188 bandings,118 are the polymorphism belt, accounts for 62.8%, average each DNA polymorphism belt number which directs the thing to increase is 5.90, has promulgated the sweet potato variety heredity multiplicity; construct the shape chart called UPGMA to reflection variety diverse , will supply to try 31 variety divisions will be 4 broad headings, has promulgated between Hunan sweet potato variety from the molecular level and with the foreign country variety between sibship.

从100个10bp的随机引物中筛选出20个扩增效果较好的引物进行扩增，共产生188条带，其中118条为多态性带，占 62.8%，平均每个引物扩增出的DNA多态性带数为 5.90条，揭示了甘薯品种的遗传多样性；根据扩增结果构建出反映品种多样的UPGMA聚状图，将供试31个品种划分为4大类，从分子水平上揭示了湖南甘薯品种之间及其与外域品种之间的亲缘关系。
