摘要
为实现茶树种质资源的系统分类,利用17对SSR对94个茶树种质资源进行亲缘关系、遗传多样性与群体结构分析。结果表明:6个自然杂交后代群体的亲缘关系分为3种类型,第1种茗科1号(金观音)、金牡丹、悦茗香和白鸡冠的自然杂交后代群体与其亲本关系密切;第2种福云6号自然杂交后代群体分别与福云6号和乌龙茶资源亲缘关系较近;第3种紫玫瑰自然杂交后代群体未与紫玫瑰聚类在一起;武夷山茶树种质资源群体遗传多态性最高,分别与肉桂和矮脚乌龙亲缘关系较近。群体结构分析表明,94个茶树种质资源分为3类群,分别为闽南高香资源类群属性、闽北乌龙茶种质资源类群属性、乌龙茶与绿茶种质资源混合类群属性。
For a systematic classification on the tea germplasm collection,17 pairs of SSR primers of the 94 tea cultivars were analyzed for their genetic relationships and diversity as well as population structure.On genetic relationship,the 6 natural hybrids were divided into 3 types,i.e.,(1)the hybrid progenies of Jinguanyin,Jinmudan,Yuemingxiang and Baijiguan that were closely related to their parents,(2)the progenies of Fuyun No.6 that were closely related to Fuyun No.6 or Oolong tea,and(3)the progenies of Zimeigui that were not close to Zimeigui.The teas from Mt.Wuyi had the greatest genetic polymorphism among all and were closely related to either Rougui or Aijiaowulong.The population structures of these 94 tea germplasms could be categorized into 3 clusters.They included one of the highly aromatic teas from Southern Fujian,one of the oolong teas from Northern Fujian,and another of the other oolong and green teas.The information would aid in identifying the resources and molecular markers of the tea germplasms for breeding new varieties.
