Tiangong Mi belongs to Euro-American hybrids and is a new mid-ripening, table grape with excellent appearance. The seeding was derived from a cross between Zao Tian and Ju Meigui in 2009 at experimental field. Through artificial hybridization pollination, 430 hybrid seeds were got. It was initially selected for blue-black, peelable, much juice, and slight foxy flavor in 2013. From 2014, it was secondary selected. After regional adaptability testing at three sites(including Haining, Yuyao and Haiyan county) over four years from 2017 to 2020, it was finally named Tiangong Mi. The shoot tip of Tiangong Mi is closed and tip anthocyanin color intensity is medium with very dense hair. The upper surface of a young leaf is green color and creeping hairs between main veins of reverse side are very dense. The shape of the mature leaves is subcircular, green and flat. The average length of leaves is 14.5 cm and the width of leaves is 18.8 cm. The petiole sinus is closed. The shape of teeth is both sides straight. Number of leaf lobes is 5. Upper lateral sinus of leaf is overlapped, while lower lobed open.Anthocyanins of main veins on leaf surface are weak. The color of dorsal side of shoot internodes is green with red strips. Its flowers are bisexual and inflorescence usually is born in third node. Its clusters are cone, medium compact with the average weight of 452.5 g. The average berry weight with blueblack in color is 8.7 g, maximum fruit weight is 12.5 g, and fruit shape index is 1.1. The flesh is medium and much juice with slight foxy flavor. The content of soluble solid in berry is 20.2%, acid content is 4.35 g·kg^(-1) and vitamin C content is 87.0 mg·kg^(-1). Berry quality is excellent. The fruit ripens at early of August in northern Zhejiang area. The number of inflorescence is 1.2, germination rate is 78.2% and proportion of fruit branches is 99.7%. It has vigorous growth and strong disease resistance and is suitable for cultivation in the Yangtze River Delta region with hot and humid climate in south China.
