 note = {A seed collection from wild apple trees (Malus species) was carried out at mountain area of Kazuno City of Akita Prefecture, Ajiro Town and Matsuo Village, Shizukuishi Town and Takizawa Village, and Tamayama Village of Iwate Prefecture in 1989. The Seeds from 72 wild trees were collected. In addition to the seeds, the budsticks were obtained from 5 trees planted in private and public garden in Isikawa and Miyagi prefectures. Among 72 wild trees, 12 trees were identified as Malus sieboldii REHD. and 60 trees were considered to be Malus sieboldii REHD. var. arborescence REHD. Within groups, there are not so large variation in leaf shape, but small or clear differences on the leaf size and fruit characteristics. The Nakataki area of Kazuno City is famous as a treasury of wild apple trees. However, no trees were discovered there because of the development for pasture. At Appi Highland, which bestrides the boundary between Ajiro Town and Matsuo Village, 60 trees within about 400 wild ones were marked and their seeds were collected. The Malus sieboldii REHD. var. arborescence REHD. was dominated at high sea level in this area and Malus sieboldii REHD. existed at the foot of the mountain. At present, Appi Highland is developing as resort area and many down hill skiing courses and golf courses had been constructed. Furthermore, many beef cattles are pastured in summer time. In near future, there is a fear of disappearance of wild apple trees. In forest of the Koiwai Stock Farm, Shizukuishi Town, several wild apple trees were found and we collected seeds from 7 trees. Among them, 2 trees were classified as Malus sieboldii REHD. Only 5 trees were subjected to seed collection at Gando Lake district, Tamayama Village. The wild trees grown in this area are mostly Malus sieboldii REHD. var. arborescence. The budsticks of 4 Malus tschonoskii were obtained from the botanical garden of Tohoku University. Another one budstick was obtained from the tree planted at a private garden in Kanazawa City, Ishikawa Prefecture. The history and the species name of this tree are not clear, but it is considered to be introduced from China in ancient time. The collections of budsticks are expected to graft onto dwarfing rootstocks and the seeds will be sown at Morioka Branch, Fruit Tree Research Station, in 1990.},
