| 摘 要： | 采用RAPD分子标记方法和形态性状数量聚类分析的方法对10个不同品种的朱蕉种质资源进行了亲缘关系的研究，研究的结果如下: 40条引物共扩增出126条条带，其中多态性带为119条，多态性百分率为94.4 %。同时对25个形态性状进行了统计分析。对RAPD实验结果和形态统计的结果分别采用UPGMA法聚类分析,聚类的结果类似。

| Abstract: | In this study, genetic relationships among 10 cultivars of Ti plant (cordyline fruticosa) were estimated on the basis of morphological characters and RAPD data. Twenty five morphological characters were analyzed with an unweighted pair-group method using an arithmetic average (UPGMA). For RAPD analysis, forty 10-mer random primers were selected and 126 polymorphic bands, ranging from 0.2 kbp to 2.0 kbp, were obtained. UPGMA cluster analysis using Nei and Li's distance coefficient were then performed. Moreover, the results based on different data were similar. |
