摘要: 对12份莲雾资源和2个莲雾近缘种进行了ISSR分析, 18条引物共扩增出459个位点, 其中多态性位点435个(94.77% ) 。利用UPGMA聚类分析表明: 蒲桃、马六甲蒲桃与莲雾分属于3个不同的组; 12个莲雾品种和品系又分成4个亚组, 这与传统分类学上按照果实成熟期的划分结果基本一致。

Abstract: ISSR analysis with 18 primers to 12 wax apple ( Syzygium samarangense Merr. et Perry) germplasm and 2 closely related species p roduced 459 unambiguous bands, out of them 435 (94.77% ) were polymorphic. The dendrogram with UPGMA method showed these accessionswere divided into 3 groups; and
12 cultivars and varieties of wax apple were further divided into 4 subgroups, as was fundamentally accorded with the traditional classification based on fruit-ripening period.
