Seed Germinated
Okitsu Wase originated in 1940 as a nucellar seedling of Miyagawa Wase satsuma at the Horticultural Research Station in Okitsu. M. Kajiura and T. Iwasaki had pollinated Miyagawa with Poncirus trifoliata, but the selected Okitsu plant arose from a nucellar embryo rather than from the sexual hybrid embryo.
