摘　　要：利用11对SSR引物对84个枣品种进行分析,共检测到37个多态性位点,PIC值变幅为0.19-0.67,平均为0.48。依照枣原产地将其分为4类,遗传一致度为0.928 6-0.993 5,遗传多样性表现为华北地区〉华中地区〉华东地区〉西北地区,其中华北地区与华东地区的亲缘关系最近。基于UPGMA法聚类分析表明,11对SSR引物可以区分本试验中82.3%的枣品种,其遗传距离为0.00-0.52,均值为0.15,但并没有依照原产地完全区分开。Polymorphisms of 84 Chinese jujube were detected with 11 pairs of SSR primers . Totally ,37 polymorphic alleles were revealed .Polymorphism information content values of the primer pairs ranged from 0 .19 to 0 .67 ,with an average of 0 .48 .The 84 Chinese jujube were divided into four populations by their place of origin ,and their Nei′s genetic identity ranged from 0 .928 6 to 0 .993 5 .The parametric level of genetic diversity was ：North China〉Central China〉East China〉Northwest ,and the genetic relationship between the North China and the East China was the closest .UPGMA cluster analysis showed that 82 .3% of Chinese jujube were distinguished ,and the genetic distance among cultivars ranged from 0 .00 to 0 .52 , with an average of 0 1.5 .However ,these varieties were not distinguished according to the method of origin classification .
