Population structure of 117 domesticated and wild apples. a Neighbor-joining phylogenetic tree constructed using SNPs at fourfold degenerate sites. Each species group is color coded, with red squares representing rootstocks and red dots scions. b Principal component analysis (PCA) of the 117 apple accessions. c Bayesian model-based clustering of the 117 apple accessions with the number of ancestry kinship (K) from 3 to 5. Each vertical bar represents one apple accession and the x axis shows different apple accessions. Each color represents one putative ancestral background and the y axis quantifies ancestry membership.
