摘要：
Analysis of genetic diversity and population structure amongQuercus fabripopulations is essential for the conservation and utilization ofQ. fabriresources. Here, the genetic diversity and structure of 158 individuals from 13 natural populations ofQuercus fabriin China were analyzed using genotyping-by-sequencing (GBS). A total of 459,564 high-quality single nucleotide polymorphisms (SNPs) were obtained after filtration for subsequent analysis. Genetic structure analysis revealed that these individuals can be clustered into two groups and the structure can be explained mainly by the geographic barrier, showed gene introgression from coastal to inland areas and high mountains could significantly hinder the mutual introgression of genes. Genetic diversity analysis indicated that the individual differences within groups are greater than the differences between the two groups. These results will help us better understand the genetic backgrounds ofQ. fabri.
