“Zuo You Hong” is a new variety bred from [(Mountain - Europe) F1 × Mountain Grape] F2 generation. Ear weight average 144.8g, fruit weight 1.36g, soluble solids 18.5% ~ 24.4%, total acid 1.191g ~ 14.47g / L, juice yield 66.4 ~ 70.2%. Can be used to make dry red wine, good quality wine. Disease resistance, precocious, growth period 119 ~ 128d. The result was 86.7% and the coefficient of result was 1.92. The average yield of 6-year-old trees per hectare is 15.16t ~ 19.64t, and that of 3 ~ 6-year-old trees is 12.0 ~ 14.13t per hectare. Cold hardiness, high yield and disease resistance.
