Population structure across pepper varieties. a Principal component analysis (PCA). b Population structure inferred using STRUCTURE. All varieties were divided into two main populations (Pop1 and Pop2) when K = 2, which was the optimal K. The populations were subdivided into five subpopulations, Subpop1~Subpop5, which correlated with fruit shape. c Phylogenetic tree analysis. The tree was produced using the neighbor-joining method based on the 92 perfect SNPs. The scale bar indicates simple matching distance
