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。
In this study, genetic relationships among 10 cultivars of Ti plant （cordylinefruticosa） were estimated on the basis of morphological characters and RAPD data. For RAPD analysis, forty 10-mer random primers were selected and 126 bands, within 119 polymorphic bands and 94.4% polymorphism rate, were obtained. Twenty five morphological characters data were also recorded. The RAPD and morphological characters data were then respectively analyzed with an unweighted pair-group method using an arithmetic average （UPGMA）. The results based on different data were similar.
