| 摘 要： | 利用ISSR技术对茉莉花30份材料的遗传多态性进行了分析.从100个随机引物中筛选出10个多态性引物,共扩增出70条DNA条带,其中34条为多态性条带,占48.57%,平均每个引物扩增出3.4条DNA带.按照相同迁移位上有扩增带记为1、无带为0的方法构建ISSR表型数据的矩阵,用NTSYSpc 2.0软件对茉莉花30个材料进行UPGMA聚类分析.计算出30份材料的遗传相似系数为0.86～0.98,平均相似系数为0.91,并在此基础上建立了聚类分析树状图,在相似系数0.86处,将30份材料划分为A、B 2大聚类组. |

| Abstract: | ISSR assessment of genetic variations in 30 varieties of Jasminum sambac was carried out.Ten primers were screened from 100 arbitrary primers,and a total of 70 DNA bands were amplified,among which 34(48.57%)were polymorphic.The average number of DNA bands amplified by each primer was 3.4,and the average genetic distance among 30 varieties was 0.91.Based on UPGMA cluster analysis of 70 DNA bands amplified by 10 primers,a DNA molecular dendrogram was established,which divided the 30 varieties into two groups:... |
