Genetic diversity analysis and core collection construction of tea plant from the Yunnan Province of China using ddRAD sequencing.

ABSTRACT: Tea plants are economically important woody plants that originated in southwestern China. The Yunnan Province in China is regarded as the central origin of tea plants owing to the abundance and diversity of the tea germplasm present in this region. However, there is a lack of knowledge regarding the genetic diversity and evolutionary relationships among tea plants in this region. Here, a total of 266,397 high-quality single nucleotide polymorphisms were obtained using double digest restriction-site associated DNA sequencing from 468 tea accessions collected from Yunnan. The phylogenetic relationship and population structure of the 468 tea accessions revealed remarkable inter- and intraspecific introgression across different sect. Thea species. We found that Camellia taliensis (W. W. Smith)
