摘要
用RAPD分子标记技术分析了8个一串红品种(系)DNA的多态性,从200个10碱基随机引物中筛选出多态性高的30个引物,扩增出162条DNA谱带中,119条是多态的,多态性占73.5%,通过聚类分析,获得品种(系)聚类树状图;聚类分析的结果,按照株高可将供试的8个一串红品种(系)分为两大类。
The genetic relationships between 8 cultivars and strains of Salvia splendens were studied by using RAPD （random amplified polymorphic DNA） technique. 162 bands including 119 polymorphic bands were detected by 30 RAPD primers that were selected from 200 RAPD markers, and the genetic diversity was 73.46%. The result of clustering analysis by UPGMA method showed that the eight cuhivars and strains were divided into two groups based on height of plant and its color.
