摘　　要：为了揭示绿玉树种质间的差异,应用ISSR标记对国内12份绿玉树品系的亲缘关系进行了分析,结果表明:12份绿玉树品系的遗传相似系数在0.53～0.98之间,且明显分为2个类群,而第二类群又可分为5个亚类群;我国绿玉树种质间存在丰富的遗传变异。本研究为对绿玉树进行有效的遗传改良提供了基础。In order to reveal the genetic differences of the Euphorbia tirucalli germplasms,the genetic diversity of 12 Euphorbia tirucalli L.strains was analyzed using ISSR marker.The results showed that the genetic similarity among them ranged from 0.53 to 0.98,and these 12 germplasms were classified into 2 groups and the second group could be further classified into 5 sub-groups.The genetic diversity of Euphorbia tirucalli germplasm is rich in China.This research established a foundation for the effective genetic improvement of Euphorbia tirucalli L.
