ツバキとチャとの種間交雑によるつばき農林１号 '春待姫' の育成経過とその特性 Breeding Process and Characteristics of Camellia Norin No.1 'Harumachihime' by Interspecific Hybridization between Camellia japonica and C. sinensis 柴田, 道夫 シバタ, ミチオ SHIBATA, Michio 間, 竜太郎 アイダ, リュウタロウ AIDA, Ryutaro 岸本, 早苗 キシモト, サナエ KISHIMOTO, Sanae 谷川, 奈津 タニカワ, ナツ TANIKAWA, Natsu 小野崎, 隆 オノザキ, タカシ ONOZAKI, Takashi 家弓, 實行 カユミ, サネユキ KAYUMI, Saneyuki ツバキ チャ 種間雑種 斑入り 縦絞り 冬～春咲き 極小輪 In order to breed new miniture camellia cultivar with early flowering property, interspecific hybridization between Camellia japonica L. and C. sinensis was (L.) O.Kuntze conducted. Nine hundred and thirty -five flowers of C. japonica were crossed with 3 cultivars of C. sinensis in 1990-1991. Twenty-one interspecific hybrid seedlings were planted to open field in 1993 and their characteristics were investigated for the following selection. The seedling derived from the cross between C. japonica 'Komomiji' and C. sinensis 'Yamatomidori' was finally selected in 1998 and was registered as Camellia Norin No.1, 'Harumachihime' in 2002. 'Harumachihime' shows the intermediate characteristic plant form between C. japonica and C. sinensis. The flower color pattern of 'Harumachihime' is striated-speckled of pink (JHS color chart No.9504) on a white ground (JHS color chart No.2201). This is the first hybrid with speckled flower color in this cross combination. Flower diameter is approximately 3 cm. The number of petals is 6 to 7. The natural flowering time of 'Harumachihime' is between the beginning of December and the end of April in Mie prefecture. 'Harumachihime' is easily propagated by cutting and has vigorous growth habit. 独立行政法人 農業技術研究機構 花き研究所 2003-10-31 jpn departmental bulletin paper VoR https://doi.org/10.24514/00001405 https://repository.naro.go.jp/records/1442 10.24514/00001405 10.24514/00001405 1347-2917 花き研究所研究報告 Bulletin of the National Institute of Floricultural Science 3 1 9 https://repository.naro.go.jp/record/1442/files/frc_report_No3p1-9p.pdf application/pdf 9.1 MB 2019-03-14
