内容記述 |
'Kanshu' is a pollination constant non-astringent (PCNA) type of Japanese persimmon (Diospyros kaki Thunb.) cultivar released by the Department of Grape and Persimmon Research of the National Institute of Fruit Tree Science (NIFTS), Akitsu, Hiroshima, Japan, in the year 2002. The fruit is distinguished by its sweetness, early ripeness, no fruit cracking habits, and excellent eating quality. 'Kanshu' resulted from the cross 'Shinshu' x 18-4 made in 1986. 18-4 is a PCNA selection from the cross 'Fuyu' x Okitsu-16. Okitsu-16 is a PCNA selection from crossing 'Okugosho' x 'Hanagosho'. 'Kanshu' was primarily selected at NIFTS (Akitsu) in 1994, designated as Kaki Akitsu-14, and was tested at 27 locations in 25 prefectures under the Fifth Persimmon National Trial initiated in 1996. It was ultimately selected, and released as 'Kanshu' in 2002, and registered as No.12980 under the Seeds and Seedlings Law of Japan in 2005. The 'Kanshu' fruit ripens in late October, earlier than 'Matsumotowase-Fuyu', and later than 'Izu'. Its fruit is moderately flat-shaped, weighing an average of 244g (slightly less than the fruit of 'Matsumotowase-Fuyu') at NIFTS (Akitsu). The skin color is orange at harvest time, having a value of 5.5 on the color chart for 'Fuyu' (Yamazaki and Suzuki, 1980, Bull. Fruit Tree Res. Stn. A7:19-44) at fruit apex. The flesh is moderately fine and moderately juicy. Soluble solids content in juice averages 18%, higher than any other leading cultivar in Japan except 'Saijo'. The fruit is PCNA, that is, its astringency loses naturally and stably on the tree, irrespectivelly of the number of seeds it contains when the tree is grown in warm areas. 'Kanshu' can be commercially grown in 'Fuyu' and 'Matsumotowase-Fuyu' production areas. Fruit cracking at the calyx end, which is a serious physiological disorder in 'Izu' and 'Matsumotowase-Fuyu', does not occur in 'Kanshu'. Fruit cracking at the stylar end does not occur, too. The occurrence of fruit skin darkening, a physiological disorder, was high in 'Kanshu'. The ratio of fruit with darkened skin averaged 40% in the national trial, which was higher than 'Izu' and 'Matsumotowase-Fuyu'. The shelf life of 'Kanshu' averaged 15 days at ambient temperature in the national trial, which was longer than that of 'Izu' and shorter than that of 'Matsumotowase-Fuyu'. The tree is moderately vigorous but less vigorous than 'Fuyu'. It is intermediate between upright and spreading in shape. It easily produces many female flowers every year, and some male flowers. The fruits have high parthenocarpic ability. Fruit dropping in the early fruit-developmental stage in June and July is rare for fruit that were subjected to flower thinning at around 13 leaf/flower ratio. Planting pollinizer trees is not needed for stable fruit production. Fruit dropping in the late fruit-developmental stage after July is rare in 'Kanshu'. |
