‘ Taiho’ is a pollination constant non-astringent (PCNA) type of Japanese persimmon (Diospyros kaki Thunb.) cultivar that was released by the National Agriculture and Food Research Organization Institute of Fruit Tree Science (NIFTS) , Akitsu, Hiroshima, Japan, in 2014. ‘ Taiho’ resulted from the cross of Kaki Okitsu-20 × ‘ Taishuu’. ‘ Taiho’ was initially selected and designated as Kaki Akitsu-25, and was tested at 26 locations in a national trial. It was ultimately selected and released as ‘ Taiho’, and registered as No. 24349 under the Plant Variety Protection and Seed Act of Japan in 2015.
The ‘ Taiho’ fruit ripens in late November, which is comparable to ‘Fuyu’ at NIFTS, Akitsu. Its fruit is flat-shaped and weighs 336 g at Akitsu. The skin color is orange at harvest time. The soluble solids concentration in juice averages 16.6%, which is also comparable to that of ‘Fuyu’. The flesh is intermediate between fine and course, crisp, and juicy. Fruit firmness is 1.55 kg, lower than that of ‘Fuyu’ (1.93 kg) . Shelf life of ‘ Taiho’ is longer than that of ‘Matsumotowase Fuyu’ and averaged at 30 days. Fruit cracking at fruit apex is rare, and that at the calyx end is 2% on average, a value lower that ‘Matsumotowase Fuyu’ (13%) and comparable to ‘Fuyu’ (3%) . Fruits with skin stains averaged at 36%, and the main cause of the stain is broken line-like cracks on the skin surface.
The tree vigor is medium to moderately strong. ‘ Taiho’ produces many female flowers but no male those ones. Fruit drops in the early stage of fruit development are little, and those in the late stages are rare. Due to its high parthenocarpic ability, the tree produces seedless fruits easily when no pollinizers are present.
