摘　　要：湘刺3号是从怀化市中方县桐木镇通过实生选种得到的一个极晚熟刺葡萄新品种。果穗多呈圆柱形,少部分有副穗,松紧适中,成熟时果皮呈蓝黑色,果粉薄,果皮厚,平均穗质量163 g,平均单粒质量3.4 g,果形指数1.1(纵径/横径),每颗果实中含种子2~3粒,多为3粒,种子颜色黑褐色。可溶性固形物含量(w,后同)15.2%,可滴定酸含量0.28%。果实发育期130 d左右,3月下旬至4月初萌芽,4月底至5月上旬开花,9月下旬果实成熟。该品种抗旱性强,极抗多湿土壤;抗黑痘病、白粉病、炭疽病、灰霉病能力强,但不抗霜霉病;抗虫性强,但不抗根瘤蚜。适宜在湖南、贵州、四川、江西、福建、湖北、云南、广东、广西、重庆等省份的葡萄产区春、秋两季种植。The Xiangci No.3(Vitis davidii)is a new extremely late-ripening spine grape cultivar se-lected from Tongmu Town,Zhongfang County,Huaihua City.Different from the wild V.davidii re-sources which are dioecious,this cultivar has perfect flowers,with high yield,and its fruits can be used as table grape or for wine making.Xiangci No.3 was initially selected from occasional seedlings in 2012 for its hermaphrodite flower and very late ripening date.The original tree was about 20 years old,and then propagated by grafting or cutting.The field trials were carried out afterwards.It was reg-istered as Xiangci No.3 by The ministry of Agriculture and Rural Affairs of the P.R.C.in June,2020.The branches and petioles are covered with prickles,and they are erect or slightly curved at the apex with a length of 2-4 m.The young leaves are bright reddish brown and shiny.Only the veins on the back of the leaves have sparse pubescence,and there are no villi between the veins.The first inflores-cence is located at 3-5 nodes.Each shoot has 1-2 inflorescences.The mature leaves are cuneate-shaped,trifid,the leaf color is green,and the leaf edge is lightly rolled downward,moderately thick.The leaf edge is serrate and projecting laterally.The petiole depressions are mostly open,and V-shaped.The clusters are mostly cylindrical,with a small number of cylindrical-winged,moderate tight-ness.The peel of fruit is thick and covered with thin powder,and it is easy to separate from the flesh.The flesh is pliable and difficult to separate from the seed.The average cluster weight is 163 g.The average single berry weight is 3.4 g,and the fruit shape index is 1.1(longitudinal/transverse diameter).There are 2.8 seeds in each fruit on average,and the seeds are dark brown in color,with no transverse groove and obvious seed umbilicus.In winter,the branches are yellowish brown and oval in cross sec-tion.The annual branches bear slender prickles of medium density.The juice yield is 68%,the content of soluble solid is 15.2%,and the content of titratable acid is
