‘Ruiduzaohong＇is a purplish red,early to middle season table grape cultivar（Vitis vinifera） with good eating quality. The original plant was selected from a cross between‘Jingxiu＇and‘Xiangfei＇in 1998 at the vineyard in Institute of Forestry and Pomology,Beijing Academy of Agriculture and Forestry Science（BAAFS）. The seedling was planted in 2001 and began to produce fruits in 2003. It was selected in 2005 for its large berry,good skin colour and crisp flesh. In 2006 it was grafted onto 5-year-old rootstock‘5BB＇for trials and the cultivars‘Jingxiu＇and‘Yatomi Rosa＇were also included as controls.From 2009 it was evaluated in regional trials under the name of‘26-3-4＇in the districts of Pinggu,Tongzhou,Daxing and Shunyi. It was finally released as‘Ruiduzaohong＇after the validation by the Committee of Beijing Cultivar Registration.‘Ruiduzaohong＇is a diploid V. vinifera. The vigour of the vine is medium. The shoot tip is half open with heavy hair,the shoot is half upright,distribution and intensity of anthocyanin coloration in shoot tip is heavy,density of prostrate hairs on tip is very sparse,erect hairs on tip is absent. The tendril is discontinuous and bifurcated,the color is near yellow-green. The bud is slightly pointed and slightly held out,anthocyanin coloration of buds is strong. The color of dorsal and ventral side of internodes is green with red strips. The upper surface of a young leaf is pea green（R.H.S. 61/2） color while the under surface of a young leaf is Spinach 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 medium,density of prostrate hairs between veins at lower surface is sparse,erect hairs on veins at lower surface is absent,prostrate hairs on veins at lower surface is very sparse,average intensity of anthocyanin coloration of six distal leaves prior to flowering is weak. The shape of the mature
