カンキツ新品種 \u27はれひめ\u27

Harehime\u27 is a relatively new citrus cultivar released in 2001 by the Department of Citrus Research, Okitsu, National Institute of Fruit Tree Science, National Agriculture and Bio-oriented Research Organization. It originated from a cross between\u27E-647\u27（\u27Kiyomi\u27x\u27Osceola\u27） and\u27Miyagawa wase\u27，made in 1990 at the Okitsu Branch of the Fruit Tree Research Station to breed superior early ripening mandarin-type cultivars. It was selected as a promising hybrid in 1996, and had been subjected to the local adaptability tests as\u27Kankitsu Okitsu 54\u27，conducted at 29 prefectural experimental stations in Japan. It was designated and registered as \u27Mikan Norin No.14\u27 on October 9, 2001 and also registered as No. 12069 under the Seed and Seedlings Law of Japan on June 4, 2004. The tree has medium vigor and its growth habit is between upright and spreading. It is resistant to citrus scab and somewhat susceptible to citrus canker. The fruit is about 180g in weight and the shape is oblate. The rind is orange in color, about 4 mm thick and easily peelable. The fruit surface texture is somewhat smooth. The flesh is orange in color, relatively tender and juicy. The segment membrane is relatively thin and tender. The fruit ripens in early December. Brix degree of juice is relatively low but the fruit quality is good because of low acidity and orange-like flavor. The flower has aborted anthers, and the fruit is usually seedless. When \u27Harehime\u27 flowers are pollinated with other surrounding cultivars, the fruit contains few seeds. For the production of high quality fruit, this cultivar is recommended for commercial cultivation in the districts where the rainfall is relatively low in summer and autumn. It is also recommended for growing under systems in which soil moisture can be easily controlled
