94个茶树种质资源遗传多样性与亲缘关系分析
Genetic Diversity and Relationship of 94 Tea Germplasm
摘要
Abstract
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.关键词
