a Origin of Ryukyuan and mainland Japanese citrus types (tachibana, shiikuwasha, yukunibu) derived from four ancestral populations. Thick arrows denote ancestry involving multiple individuals from a population, whereas a thin arrow stands for single individual ancestry. Dotted and solid lines from the top row denote small and significant introgression, respectively. For example, RK3 has small amount of pummelo admixture whereas kunenbo has significant pummelo introgression. The shiikuwashas are half-sibs sharing the same mainland Asian mandarin parent (RK3) but different C. ryukyuensis parents. Kunenbo (KB3) is the seed parent of the yukunibu group. b Four-way admixture map for Ryukyuan and mainland Japanese citrus types. Population code as in Fig. 1b. Tachibana genomes are characterized by both significant admixture with MS and segments of diploid C. ryukyuensis genotype. SH4 is a seedless shiikuwasha. Source data underlying Fig. 3b are provided as a Source Data file.
