A total of 27 samples were collected from three areas in east part of Kochi prefecture. They are grown on slope land along side the valleys or in fanners gardens. They are not forming colony but growing separately. Ages of the trees are estimated more than 70 years old. Branch and leaf samples were colJected from each of the accessions. Mature fruits were also collected from 22 out of 27 plants. The fruit of almost all the accessions were russet type except one. The fruit shape of the accessions were varied from round type to spindle type. The brix values of the fruits were ranged from 6.8 to 14.8 and the pH were ranged from 3.23 to 5.00 among the accessions. The collected plants will be grafted and assessed for the agronomic characters. departmental bulletin paper 農業生物資源研究所 2001-03 VoR application/pdf 植物遺伝資源探索導入調査報告書 17 33 38 Annual Report on Exploration and Introduction of Plant Genetic Resources 2434-7485 https://repository.naro.go.jp/record/7109/files/AREIPGR17_p33-38.pdf https://doi.org/10.24514/00006960 https://repository.naro.go.jp/records/7109 jpn 10.24514/00006960
