Main citrus species growing in Ogasawara Islands are C. sinensis Osbeck, C. grandis Osbeck, C. aurantium L. and lemon-like cultivars. Most of them were planted in backyard or in once garden except for the lemon. Characteristics of the lemon named Kikuchi lemon' are similar to C. meyeri hort. ex Y. Tanaka. The lemon is now in the spotlight as a special product of Ogasawara Islands. C. aurantium L. is adopted to climate of Ogasawara. Two or three fruit types of C. aulantium were observed. Some old trees of 'Ogasawara orange' are surviving in once gardens and orchards. Among them a tree growing in near Minamizaki has been noticed because of its large fruit and quality. A total of 7 germplasm were collected during exploration.}, pages = {57--75}, title = {小笠原諸島におけるカンキツ遺伝資源の調査}, volume = {18}, year = {2002}, yomi = {ネスミ, ヒロヒサ and ハラシマ, コウイチ and ワダ, ミノル and キクチ, マサト and トモナガ, シンジ and ヨシダ, トシオ} }
