| 摘 要： | 利用11对SSR引物对喀什、和田和库车3个新疆栽培杏( Prunus armeniaca L. ) 品种亚群进行了分子系统学研究。结果表明: 各位点平均期望杂合度(He = 0.2364) 显示新疆栽培杏群体具有较高的遗传多样性水平。根据基因分化系数(Gst = 0.1508) 值, 新疆杏各品种亚群的遗传分化主要存在于亚群(84.9%) 内。基于Gst测得的基因流Nm 为2.3666, 人为通过种子引种可能是其基因交流的主要方式。根据果实形态和地理起源对新疆杏进行传统分类并不能完全反映出新疆杏品种间的亲缘关系。

| Abstract: | Eleven Prunus simple sequence repeat (SSR) primer pairs have been used in the molecular characterization of 30 apricot (Prunus armeniaca L.) varieties from south Xinjiang Uygur Autonomous Region, China. A higher level of genetic diversity was revealed by Nei's gene diversity (He=0.2364). The Gst (Gene Divergence) of 0.1508 indicated that genetic variation existed mainly within sub-groups (84.9%).The modest amount of gene flow (Nm=2.3666) based on Gst was discovered. It was proposed that artificial introduction by seeds was probably the main way of gene flow. Consequently, traditional morphological and geographical classification can not completely reflect the genetic relationship between apricot varieties native to Xinjiang. |
