| 为弄清海南花生种质资源与国内外花生种质资源的遗传多样性及亲缘关系，创新利用海南花生
资源，用18 对SSR 引物评价了海南和国内外45 份花生种质资源，平均每对引物扩增多态性条带1.7 条，平
均多态性信息量（PIC）为0.459；居群遗传多样性分析显示，山东和海南文昌居群的遗传多样性最高，其次
是河南居群，遗传多样性最低的是海南儋州居群；16 个花生居群总遗传多样性主要来自于居群间的遗传变异
（72.46%），居群间的基因流动（Nm=0.1900）较少；居群和种质资源聚类分析结果基本一致，亲缘关系与地
理位置关系不大。 |

| In order to clarify the genetic diversity and the relationship between Hainan peanut germplasm resources
and other regions，and use effectively peanut resources in Hainan，45 peanut germplasm resources were evaluated by
using 18 pairs of SSR primers，polymorphic bands each primer were 1.7，the average polymorphism information content
was 0.459. Population genetic diversity analysis showed that the genetic diversity of Shandong and Wenchang population
was the highest，followed by Henan，Danzhou population was the lowest. Genetic variation of peanut among populations
（72.46%）was the main component of total genetic diversity of 16 populations，the gene flow among populations
（Nm = 0.1900）was less. Cluster analysis results of germplasm resources and populations were basically the same，
there was no clear relationship between genetic relationships and geographic locations. |
