摘　　要：‘紫金早生’是‘金星无核’通过化学诱变选育出的早熟、无核葡萄新品种,欧美杂种。果穗圆锥形,较整齐,平均单穗质量317.4 g,果粒圆形或椭圆形,紫黑色,平均单粒质量5.2 g,果皮中等厚,果肉质地较软,有较浓的玫瑰香味,平均可溶性固形物含量为17.2%,可滴定酸含量为0.66%。在南京地区,7月中旬果实成熟,早果性及丰产性强,抗病性强。＇Zijin zaosheng＇ is an early-ripening and seedless grape with high yield, strong pathogen resistance and rose-fragrant. The original plant was selected from the variation of ＇Venus Seedless＇ grape in Institute of Horticulture, Jiangsu Academy of Agricultural Sciences （JAAS）. In 2000, stem-segment with single bud of ＇Venus Seedless＇ grape was treated by 0.2% colchicine, and 42 single plants were obtained in 2001. These signal plants began to produce fruits in 2003. After three years observation, it was selected in 2006 as for its seedless, strong rosefragrant, good comprehensive characters, stable fruit bearing and strong pathogen resistance. From 2008, it was evaluated in regional trials under the name of ＇3-2D-05＇ in Lishui, Jiangning and Wuxi. In November of 2015, it was put on records by the fruit, tea arid flower variety appraisal committee of Jiangsu province and named ＇Zijin zaosheng＇. ＇Zijin zaosheng＇ belongs to V. vinifera - V. labrusca type, diploid plant and bisexual flower.

Adult leaves are medium size and tend to nearly triangle, three lobes, superfissure, oval hollow petiole is mild overlapping, serration on the leaf edge is short, both side of the serration are bossed. There is no or little anthocyanin in the principal vein of leaves surface. Creeping and vertical villi is very heavy among the principal vein of leaves back. The distribution of tendril is inconsecutive. ＇Zijin zaosheng＇ has conical cluster, the average cluster length is 16.6 cm, average cluster wide is 9.4 cm, average cluster weight is 317.4 g. The fruit grain is round or short-ellipse, the cluster is compact, uniform size, pericarp color is purple-black, and average grain weight is 5.2 g. Bloom is thick, and pericarp thickness is medium.
