Lilium longiflorum ‘Hinomoto’, the major lily cultivar in Japan, is regarded to have originated from natural individuals on Yakushima Island, and shows strong self-incompatibility; however, it was recently demonstrated that a population on Yakushima Island is dominant with weakly self-incompatible and completely self-compatible individuals, and this fact conflicts with the view that the strong self-incompatible ‘Hinomoto’ originated from Yakushima Island. The data by morphological and genetic analysis in this study indicate that ‘Hinomoto’ is genetically and morphologically different from natural individuals on Yakushima Island, but indicate that the origin of ‘Hinomoto’ could have been from any of the islands in the southern Ryukyu Archipelago.
