dc.description.abstract[中文文摘]用随机多态DNA(RAPD)标记方法对11个紫菜(Porphyra)样品进行遗传多样性检测,从46个随机引物中筛选出27个有效引物,共扩增出282条DNA带,其中多态位点224个,占79.4%。用类间平均链锁法对各样品间的遗传距离进行聚类分析。结果显示,2个条斑紫菜之间的亲缘关系很近,遗传相似系数达98.1%,和坛紫菜的亲缘关系较远;坛紫菜不同样品间的遗传相似系数在75.8%~90.6%之间,表明坛紫菜种质资源具有丰富的遗传多样性,是良种选育的遗传基础。[英文文摘]The genetic diversity of 11 Porphyras samples were confirmed by random amplified polimorphic DNA(RAPD) markers. 27 primers were screened from 46 arbitrary primers, and a total of 282 DNA bands were amplified, among them 79.4% were polymorphic. The genetic data were analyzed by means of similarity, in a dendrogram was using between groups linkage method. The result showed that a close relationship existed between two cultivears of Porphyra yezoensis and the genetic coefficient comparability was 98.1%, while the genetic diversity level in Porphyra haitanesis was relatively high.zh_CN
