'Taiten' resulted from the cross of 'Kurokuma'×'Taishu'. The clone was initially selected and designated as Kaki Akitsu-21, and was tested at 24 locations in a national trial. It was ultimately selected and released as 'Taiten', and registered as No.17493 under the Plant Variety Protection and Seed Act of Japan in 2009. The 'Taiten' fruit ripens in late November, comparable to 'Fuyu' at NIFTS, Akitsu. Its fruit is flat-shaped, weighing an average of 506 g (about 1.6 times heavier than the fruit of 'Fuyu'). The skin color is yellowish orange at harvest time. The flesh is soft, moderately coarse and very juicy. Flesh firmness is 0.8 kg, a value lower than that of 'Fuyu' (2.0 kg). The soluble solids content in juice after removing astringency averages 16.5 %, a value comparable to that of 'Fuyu'grown at Akitsu. Fruit cracking at the calyx or stylar end is rare. A little extent of shallow concentric cracks on the fruit skin occurs in a considerable percentage of the fruit. Shelf life of 'Taiten' fruit after carbon dioxide gas treatment for removing astringency averaged 21 days at ambient temperature in the national trial. The tree is vigorous and very productive. 'Taiten' easily produced many female flowers every year, and very few male flowers in the trials. Fruit drop in the early fruit-developmental stage in June and July was rare for trees subjected to flower thinning at a leaf/flower ratio of approximately 13. Although the seed forming ability of 'Taiten' is high, however, its parthenocarpic ability is low; thus planting of pollinizer trees is desirable for stable fruit production.}, pages = {39--52}, title = {カキ新品種 '太天'}, volume = {14}, year = {2012}, yomi = {ヤマダ, マサヒコ and サトウ, アキヒコ and ヤマネ, ヒロヤス and ミタニ, ノブヒト and イワナミ, ヒロシ and シライシ, ミキオ and ヒラカワ, ノブユキ and ウエノ, トシヒト and コウノ, アツシ and ヨシオカ, ミカノ and ナカジマ, イクコ} }
