s： ＇ Ruidukemei＇ is a yellow green, early to middle season table grape variety （Vitis vinifera） with good eating quality. The original plant was imported from Hungary in 2000, which was the progeny between ＇Italia＇ and ＇Muscat Louis＇. The vines were propagated by cuttings and planted with the row space of 2.5 m and vine space of 1.5 m, it was very productive and had early fruiting capacity, the berries had yellow skin color and strong Muscat flavor. It was evaluated in regional trials in the districts of Yanqing, Haidian and Pinggu of Beijing, the varieties of ＇Xiangfei＇, ＇Italia＇ and ＇Pearl of Csaba＇ were also includ- ed as controls. It was finally released as ＇Ruidukemei＇ atier validation through the Committee of Beijing Cultivar Registration and has good market potential for the traits of muscat flavor and large berry. ＇ Ruid- ukemei＇ is a diploid Vitis vinifera. The vigor of the vine is medium. The shoot tip is half open with no hair, the shoot is upright, distribution and intensity of anthocyanin coloration in shoot tip is light, density of prostrate hairs on tip is medium, density of erect hairs on tip is sparse. The tendril is discontinuous and bi- furcated, the color is near yellow-green. The bud is slightly pointed and slightly held out, anthocyanin col- oration of buds is strong. The color of dorsal and ventral side of internodes is green with red strips. The up- per surface of a young leaf is pea green （R.H.S. 61/2） color while the undersurface of a young leaf is Spin- ach Green （R.H.S. 960/2） color. Average intensity of anthocyanin coloration of six distal leaves prior to flowering is weak. Density of erect hairs between veins at lower surface of 4th distal unfolded leaf is medi- um, density of prostrate hairs between veins at lower surface is strong, density of erect hairs on veins at lower surface is medium, density of prostrate hairs on veins at lower surface is strong. The shape of the mature leaves is pentagonal with undulate sides, medium thickness.
