| 摘 要： | 为了给海岛棉育种实践提供可靠的信息,采用SSR标记技术对14个已知来源的海岛棉品种的遗传背景进行了遗传多样性分析.从筛选出的41对有多态性的SSR引物中共扩增出280个等位位点,其中214个位点有多态性,占76.4;,每对引物可扩增出1～15个位点,平均6.83个等位位点.聚类分析表明,在SM相似系数0.64水平上14个海岛棉品种可聚成4类.实验证明SSR标记技术可为海岛棉育种中亲本选配,提供可靠的分子水平上的依据.

| Abstract: | The genetic relationships among 14 Sea-Island Cotton varieties were analyzed by SSRs to provide credible genetic information in breeding Sea-Island Cotton 280 distinctive loci in total were amplified f rom 41 pairs of SSR primers,and 214 were polymorphic,which accounted for 76.4 %.1 to 15 polymorphic loci could be amplified from each primer,with an average of 6.83.The 14 Sea-Island Cotton varieties could be classified into 4 groups at the level of SM=0.64 by cluster analysis.SSR markers proved to be the work of Sea-Island cotton breeding practice of matching parents,to provide a reliable basis for the molecular level. |
