Diversity represented by 306 hexaploid wheat accessions. a Geographical distribution of wheat accessions, as indicated by circles on the world map. Circle size is proportional to the number of accessions. b Phylogenetic tree of all accessions calculated from whole-genome SNPs. The colors indicate the 10 groups (G1-G10). c Principal component analysis (PCA) plot of the first two components (PC1 and PC2) of the 306 wheat accessions. d Population structure analysis with K = 10. The y-axis quantifies cluster membership, and the x-axis represents the different accessions. The order and position of the accessions along the x-axis are consistent with those in the phylogenetic tree. e Decay of linkage disequilibrium (LD) in the wheat genome. LD decay was estimated based on SNP markers from all three genomes: A genome (chr A), B genome (chr B), and D genome (chr D)
