摘要: 利用ISSR分子标记对9个观叶福禄桐品种进行遗传多样性和亲缘关系分析,从100条引物中筛选出9条稳定、多态性高的引物用于PCR扩增,共获得70条带,其中多态性条带61条,多态百分率为87.14%。聚类结果显示,品种间相似性系数为0.346 9-0.816 3,聚类结果与品种间的地理来源紧密相关,从外观形态上比较,亲缘性较近的叶形和株型相似性较高;观叶福禄桐各品种间基因型差异较小,亲缘关系较近,遗传基础相对较窄。

Abstract: In this study, nine species Polyscias leaves as experimental material, we analyzed the genetic diversity and relationship by ISSR markers, 9 stable and high polymorphism ISSR primers screened from 100 ISSR primers by optimized the system of PCR for Polyscias, a total of 70 bands were obtained by the polymorphic primers of 9 test specimens, including 61 polymorphic bands, the polymorphic percentage was 87.14%. The genetic similarity coefficients ranged from 0.346 9 to 0.816 3, suggesting that the substantial genetic divergence between some varieties. The clustering scheme showed that Polyscias had small differences of genetypes their genetic basis was comparatively narrow.

Key words: ISSR, Polyscias, foliage plants, genetic similarity coefficient, cluster analysis
