 note = {'Oriental Star' is a diploid table grape cultivar derived from V. labruscana Bailey and V. vinifera L. released by National Institute of Fruit Tree Science (NIFTS) in Japan. It has large purple berries, crisp flesh texture, high soluble solids concentration and low acidity. Its seedless berries can be commercially produced by applying gibberellic acid treatment to flower and fruit clusters in full bloom and 10 to 15 days after full bloom, respectively. It is sensitive to anthracnose and downy mildew. 'Oriental Star' resulted from a cross of Akitsu-21 and 'Ruby Okuyama' (V. vinifera) made in 1989. Akitsu-21 is a hybrid of 'Steuben' (V. labruscana) x 'Muscat of Alexandria '(V. vinifera). The original vine was primarily selected in 1997 in a NIFTS vineyard at Akitsu, and was tested as selection Akitsu-24 in 33 locations in 30 prefectures under the Ninth Grape Selection National Trial initiated in 1999. It was ultimately selected, and released as 'Oriental Star' in 2004, and registered as No.14,914 under the Plant Variety Protection and Seed Act of Japan in 2007. The 'Oriental Star' fruit ripens in late August in Akitsu. Its ripening time was 8 days and 4days later than 'Kyoho' and 'Neo-muscat', respectively, in the national trial. Berry weight averaged 10.7 g and 12.4 g in seeded and seedless fruit production in Akitsu, respectively. The berry has a neutral flavor, and crispy and juicy flesh.　Soluble solids concentration and titratable acidity averaged　around 19% and 0.4 g/100 mL, respectively. A cidity is significantly less than that of 'Kyoho'. Astringency is not sensed. Like 'Kyoho', cracking of the berry skin is unlikely to occur. Shattering of berries from clusters at full maturity is less than that of 'Kyoho'. The berry skin can slip, although not as easily as that of 'Delaware'. Its shelf life is longer than that of' Kyoho'. The 'Oriental Star' vine is vigorous and seems to have cold hardiness comparable to 'Kyoho'. Berry set is easy irrespective of the vigor of bearing shoots in seeded fruit production. Flower clusters should be trimmed and berries thinned to obtain attractive fruit clusters, as is the case for most commercial cultivars in Japan. The time taken to trim flower clusters and to thin berries are not longer than those for 'Kyoho'.},
