Genetic diversity analysis and core germplasm construction of tea plants in Lu'an.

ABSTRACT:

Background

Lu'an, as one of the two major tea-producing areas in Anhui Province, has a long history of tea planting and rich tea germplasm resources. However, the genetic diversity and population structure of local tea plants are still unclear. In order to better protect and utilize tea germplasm resources in Lu'an, 217 tea accessions from six geographical origins were used to assess genetic diversity of Lu'an tea plant germplasm through double digest restriction-site associated DNA sequencing (ddRAD-seq) technology.

Results

A total of 306,320 high quality single nucleotide polymorphism (SNP) markers were obtained. Population structure, phylogenetic relationships and principal component analysis (PCA) divided the entire population into three groups. The genetic diversity and
