 note = {Sunny Rouge' is a new early-ripening and tetraploid grape cultivar (Vitis labruscana Bailey × Vitis vinifera L.) for table use, released by the Persimmon and Grape Research Center (presently the Department of Grape and Persimmon Research) of the National Institute of Fruit Tree Science, Akitsu, Hiroshima, Japan, in 1997. The berries are seedless, medium-sized, and weigh 5-6g when the flower clusters were treated twice with 25ppm solution of gibberellic acid (GA), the first application at full bloom and the second at 10 days after full bloom. Most of the berries are seedless, weigh 3-4g, and the bunch is not well filled due to berry shattering in GA non-treated condition. 'Sunny Rouge' resulted from the cross 'Pione' × 'Red Pearl' made in 1977. 'Pione' is a mid-ripening tetraploid grape cultivar with excellent quality and the berries are very large in size. 'Red Pearl' is an earlyripening tetraploid grape of a bud-sport of 'Delaware' and the berries are small in size. 'Sunny Rouge' was selected at Akitsu in 1988 for its characters of early-ripening and large seedless berry as a result of GA treatments. It has been tested at 29 locations in 27 prefectures under the 8th grape regional trial initiated in 1992.  The vines of 'Sunny Rouge' are moderately vigorous. The color of woody shoots is dark brown. The leaves are larger than those of 'Delaware', pentagonal in shape and five-lobed. The tomental density of the leaves is lower than that of 'Delaware'. The sprouting time is later than 'Delaware', and the same as that of 'Kyoho'. The flowers are perfect and their blooming time is nearly the same as that of 'Delaware'. 'Sunny Rouge' is more resistant to downy and powdery mildews, ripe rot, and anthracnose than most of the vinifera table grape cultivars. The fruit clusters treated with GA are medium-sized (300-400g), cylindrical in shape and well filled. Berry thinning in the clusters is required slightly. The berries are elliptical and red-brown to violet red skinned. The berry skin is a slip skin and easy to be colored. The fruit ripens in mid to late August, earlier than 'Kyoho' and later than 'Delaware' at Akitsu. The flesh is firm and easier to be broken down than those of 'Delaware', and is the same as those of 'Kyoho'. Soluble solids concentration is around 19%, being as high as that of 'Delaware', and the titratable acidity is around 0.5 g/100ml, being lower than that of 'Delaware' and the same as that of 'Kyoho'. The flavor is a note of labrusca character (foxy flavor). Cracking of the berry has been observed rarely. The berries sometimes have a little bit of astringency, depending on cultural conditions. The shelf life of 'Sunny Rouge' is as long as that of 'Delaware', and longer than that of 'Kyoho'.},
