1993～1996年引进早熟、大粒、大穗鲜食葡萄新品种“京亚”。观察结果认为：“京亚”树势强，植株成形快，早熟、丰产、效益高，易栽培管理。果穗平均重470g果粒平均重9g。浆果含可溶性固形物13．5％～15．5％，品质好于巨峰。定植第3年，666．7m2产1008．9kg，第4年达1631．1kg。基本不感黑痘病、白粉病、白腐病，对霜霉病有较强抗性。抗寒力强于巨峰。萌芽到浆果成熟为111～118天，比巨峰早熟14～18天。适宜无霜期124天，有效积温2500℃以上的地区生产栽培。
From 1993 to 1996, we introduced “Beijing-Asia”, a new grape variety of early mature, big grain and big spike. Observations: “Beijing Asia” strong tree, plant forming fast, early maturity, high yield, high efficiency, easy cultivation and management. The average weight of ears 470g fruit average weight 9g. Berry contains soluble solids 13.5% ~ 15.5%, better quality than Jufeng. The third year of planting, 666.7m2 production 1008.9kg, the fourth year of 1631.1kg. Basically no sense of black pox disease, powdery mildew, white rot disease, downy mildew resistance. Hardiness stronger than Jufeng. Germination to berry ripe for 111 ~ 118 days, 14 ~ 18 days earlier than Jufeng. Suitable frost-free period of 124 days, the effective accumulated temperature 2500 ℃ above the area of production and cultivation.
