 note = {We explored the Kirishima Mountains in southern Kyūshū and collected Malus spontanea Makino. This is an endemic species whose natural habitat is limited to the Ebino-kōgen high plateau in the Kirishima Mountains. This area has been designated as a National Natural Monument. Although the natural growing habitat is deteriorating and the number of individual trees has decreased by about half, we were still able to discover 296 trees and we were able to collect scions from 11 of them. In addition, we investigated“Takanabe kaidō”, which is an undescribed plant discovered about 30 year ago. We collected scions from four cultivated trees. A total of 15 genetic resources were collected during this project.
宮崎県鹿児島県にまたがる霧島山系のえびの高原において，この箇所を唯一の自生地とするリンゴ属の固有種であり，国指定天然記念物であるノカイドウ（Malus spontanea (Makino)Makino）の探索調査を行った．自生地の生育環境は悪化しつつあり，自生個体数もこの約50年間で半減近くになっているが，296株を確認し11個体から穂木を収集した．また，同県高鍋町で約30年前に前に発見され，分類学的所属が不明であるタカナベカイドウ（Malus sp.）の探索調査も行い，栽培個体4株から穂木を収集した．以上合わせて15点の遺伝資源の収集を行った．},
