Geographic distribution and population structure of resequenced accessions from Fagopyrum species. a Geographic distributions of Tartary buckwheat accessions. Each accession is represented by a dot on the map. The spread routes are shown with blue lines, which represent from northern China to other countries. HW, Himalayan Wild accession; SL, Southwest Landraces; NL, North Landraces. b Neighbor-joining tree of 517 germplasms, including 510 Tartary buckwheat accessions and 7 other Fagopyrum species. Branch colors indicate different groups: group HW (red), group SL (green), group NL (blue), and outgroup (purple), matching the colors shown in a. c Principal component analysis of Tartary buckwheat accessions, showing the first two components. Colors correspond to the phylogenetic tree grouping. d The population structure analysis with different numbers of clusters (K = 3, 4, and 5) matches the phylogenetic tree. The x axis lists the different accessions that are consistent with those in the phylogenetic tree. e Phylogenetic tree of the outgroup species
