采用SSR分子标记技术，对福建霞浦杨梅岭国有林场柳杉初级种子园12个种源地，共计96份优良无性系植株进行遗传多样性的分析，结果表明：26对SSR分子标记检测出柳杉种子园处于较高的遗传多样性水平，共扩增得到103个多态位点。平均等位基因数3．9615个，平均有效等位基因数2．7282个；平均观察杂合度为0．4966，Shannon信息指数平均为0．9945，Nei多样性指数平均为0．5336。其遗传变异主要存在于种源内，不同种源基因分化系数为0．1670。

We used SSR molecular maker to detect genetic diversity of Cryptomeria fortunei from Fujian Xiapu Yangmeilin Na-tional Seed Orchard.96 are excellent clones collected from 12 different provenances.A relatively high level of genetic di-versity is detected in C.fortunei’s species with 26 polymorphic microsatellite loci.103 loci are polymorphic markers.Av-erage number of alleles and effective numberof alleles are 3.961 5 and 2.728 2, respectively.The mean expected het-erozygosity is 0.496 6.Shannon information index is 0.987 1, Nei diversity index is 0.536 2.The majority of genetic vari-ation is within provenance (0.167 0).
