Genetic diversity linkage disequilibrium and population structure analysis of the tea plant (Camellia sinensis) from an origin center Guizhou plateau using genome-wide SNPs developed by genotyping-by-sequencing

摘要

BackgroundTo efficiently protect and exploit germplasm resources for marker development and breeding purposes, we must accurately depict the features of the tea populations. This study focuses on the Camellia sinensis (C. sinensis) population and aims to (i) identify single nucleotide polymorphisms (SNPs) on the genome level, (ii) investigate the genetic diversity and population structure, and (iii) characterize the linkage disequilibrium (LD) pattern to facilitate next genome-wide association mapping and marker-assisted selection.
