Neighbor-joining tree based on genotyping results of plastome and nuclear genome markers. a Chloroplast genome genotype-based neighbor-joining tree of Cw and Ca populations. b Nuclear genome genotype-based neighbor-joining tree of the Cw population. Major and minor groups are represented by shaded boxes. Two sets of colored bars represent the genotypes of the chloroplast and nuclear genomes. The seven bars in each set represent genotypes identified with the 14 markers developed from the chloroplast and nuclear genomes, respectively (1: isv1, 2: isv2, 3: isv3, 4: isv4, 5: isv5, 6: isv_cp_kasp1, 7: isv_cp_kasp2, 8: isv_nc_kasp1, 9: isv_nc_kasp2, 10: isv_nc_kasp3, 11: isv_nc_kasp4, 12: isv_nc_kasp5, 13: isv_nc_kasp6, 14: isv_nc_kasp7). Colors indicating each genotype are displayed under the tree. Distribution of Cp-I-1 and Cp-II-1 in the nuclear genome tree is indicated by green and purple triangles
