 note = {Queen Nina' is a tetraploid table grape cultivar released by the National Agriculture and Food Research Organization Institute of Fruit Tree Science (NIFTS) in Japan. It has large red berries, high soluble solids concentration, and low acidity. The berries can be converted to seedless ones by applying gibberellic acid to flower and fruit clusters in full bloom and again at 10 to 15 days after full bloom. 'Queen Nina' resulted from a cross of Akitsu-20 and 'Aki Queen' made in 1992 at Akitsu, NIFTS. Akitsu-20 is a hybrid selection of 'Benizuiho'×'Hakuho'. The original vine was initially selected in 2002 in a vineyard at Akitsu, and was tested as selection Akitsu-27 in 36 locations of 34 prefectures under the 11th Grape Selection National Trial initiated in 2004. It was ultimately selected, and released as 'Queen Nina' in 2009, and registered as No. 20733 under The Plant Variety and Seedling Act of Japan in 2011. The seedless fruit of 'Queen Nina' ripens in late August to early September at Akitsu. Its ripening time was 7 days and 4 days later than 'Kyoho' and 'Pione', respectively, in the national trial. Berry weight averaged 17.6 g in seedless fruit production at Akitsu. The berry has a mild foxy flavor, easy breakable, firm, and juicy flesh. Soluble solids concentration and titratable acidity averaged around 20.6% and 0.40 g/100ml, respectively in the national trial. Soluble solids concentration is significantly higher than in 'Kyoho' and 'Pione', whereas acidity is significantly lower than in those cultivars. Astringency of the flesh is not sensed. Some berry skin cracking has been observed depending on location and year. Berry set and the degree of shatter of berries from clusters at full maturity are similar to 'Kyoho' and 'Pione'. Shelf life is almost similar to 'Kyoho' and 'Pione'. The 'Queen Nina' vine is moderately vigorous and seems to possess lower cold hardiness than 'Kyoho'. Flower cluster should be trimmed and berries thinned to obtain attractive fruit clusters as in most of the commercial cultivars in Japan. Those modifications require moderately long and medium time to made, respectively, similar to 'Kyoho' and 'Pione'.},
