摘　　要：天工翠香蜜是通过胚挽救技术从火焰无核(♀)和寒香蜜(♂)的杂交后代中选出的优质特早熟无核葡萄新品种。果穗圆锥形,平均穗质量372.5 g,最大穗质量761.0 g。果粒呈椭圆形,黄绿色,果粒整齐,果粉较薄,平均单粒质量3.2g。果皮较薄、脆、无涩味,果汁颜色无,味甜,果肉汁液多,果肉质地脆,果肉硬度中等,可溶性固形物含量(w)为20.2%~21.3%。在浙江海宁地区,3月中旬萌芽,4月底开花,6月底浆果成熟。花芽分化和丰产、稳产性均好,萌芽率92.1%,结果枝率达86.4%。Tiangong Cuixiangmi is a new diploid seedless grape cultivar,derived from the cross between the diploid seedless grape cultivar Flame Seedless(♀) and Hanxiangmi(♂),obtained by means of in vitro ovule culture-embryo rescue in Institute of Horticulture,Zhejiang Academy of Agricultural Sciences(ZAAS).In 2013,hybrid embryo rescue breeding was carried out,using Flame Seedless as the female parent and Hanxiangmi as the male parent,and obtained 143 embryo rescue hybrid seedlings.In 2014,we planted them and initially selected them as excellent lines in 2017.Through observation in 2017—2018,we screened out a superior offspring with the number of 13-15-558,which has the characteristics of excellent flower bud differentiation,early maturity,seedlessness,crisp pulp texture,fruitfulness,etc.and finally was named Tiangong Cuixiangmi.The plant has medium growth vigor.The shoot is up-right and the shoot tip is half open with hair.The color of the dorsal side of internodes is green with red strips,while the color of the ventral side of internodes is green.The upper surface of the young leaves is light red and fluffy.Mature leaves are simple,nearly round,and green.The leaf surface has medium bubble-shaped protrusion,serrated and lobed edge on both sides,with 5-lobes,the upper lobes being open,U-shaped,the lower lobes being V-shaped.Petiole depression is open at the base and the petiole is red.There is no villus creeping between the main veins on the lower side the leaf,and leaf vein contains anthocyanins.Flowers are amphoteric and inflorescence born at 2-3 nodes.The compact cluster has an average weight of 372.5 g,with the maximum of 761.0 g.The berry is elliptic shaped,yellow green,with an average weight of 3.2 g.The skin is thin,crispy,with no astringency.The flesh is medium hard,crispy,colorless,juicy and sweet.The average soluble solid content is 20.2%-21.3%.Tiangong Cuixiangmi is an early-ripening variety.Under the greenhouse cultivation conditions in Haining area,Tiangong Cuixiangmi bud breaks in mid-March,flowers in l
