Extended Data Fig. 4: Population structure and principal component analysis of cucumber accessions.
From: Graph-based pangenome reveals structural variation dynamics during cucumber breeding
a, Population structure of cucumber accessions based on SNPs, with the number of clusters (K) ranging from 2 to 6. b, Cross-validation (CV) error plotted against K for inference of population structure. c, Principal component analysis (PCA) of cucumber accessions based on SVs. d, PCA of cucumber accessions based on SNPs. The right panel shows an enlarged view of the cluster indicated by the dotted box in the left panel.
