Population structure of pedigree varieties. (a) Neighbour-joining phylogenetic trees of pedigree varieties. Japonica was used as a reference genome for phylogenetic analysis. (b) Two-D PCA plot of pedigree varieties. (c) Population structure analysis of pedigree varieties. Each color represents one population. Each variety is represented by a vertical bar, and the length of each colored segment represents the proportion contributed by ancestral populations.
