'Taiga' 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. 'Taiga' resulted from the cross of 'Kanshu' × Kaki Akitsu-19. 'Taiga' was initially selected and designated as Kaki Akitsu-24, and was tested at 28 locations in a national trial. It was ultimately selected and released as 'Taiga', and registered as No.25272 under the Plant Variety Protection and Seed Act of Japan in 2016. The 'Taiga' fruit ripens in late October, which is earlier than 'Matsumotowase Fuyu' at NIFTS, Akitsu. The fruit is flat and weighs 324 g at Akitsu and 260 g on average at the national trial. The skin color is orange at harvest time. The soluble solids concentration in juice averages 16.6% in the national trial, which is also comparable to that of 'Fuyu'. The flesh texture is fine and juicy. Flesh is soft and 1.57 kg in firmness, lower than that of 'Matsumotowase Fuyu' and 'Fuyu'. Shelf life of 'Taiga' averages at 21 days, and is comparable to 'Matsumotowase Fuyu' and 'Fuyu'. Fruit cracking at fruit apex is only 2%, and that at the calyx end is 3%; the value is extremely lower than those of 'Matsumotowase Fuyu' and 'Fuyu'. Fruits with skin stains average at 41%, caused by a cloud-like stain on the skin surface. The tree vigor is medium. 'Taiga' produces both female and male flowers, but male flowers are very rare. Fruit drops in the early stage of fruit development in June are few, and those in the late stages of development in August are few, but sometimes occur depending on locations and years. Due to its high parthenocarpic ability, the tree produces seedless fruits easily when no pollinizers are present.
