摘　　要：湘猕枣是从湖南浏阳市大围山野生软枣猕猴桃群体中选育出的新品种。果实呈长柱形,果肉绿色,成熟后果皮呈紫红色,种子附近果肉呈紫红色。果皮光滑无毛,表面蜡质具果粉。平均单果质量为25.18 g,最大单果质量为28.33g,果形指数为1.37。花后100d采收时的可溶性固形物含量(w,后同)为13.13%,总酸含量为1.13%,后熟期果实可溶性固形物含量最高可达26.5%,平均可溶性固形物含量为23.34%,干物质含量为22.28%。单个果实平均含有种子130粒,维生素C含量为36 mg·100 g^(-1),果柄长度为11.14~26.29 mm。该品种抗逆性强,溃疡病抗性强于米良1号,可作为鲜食和加工品种。Xiangmizao is a new tara vine cultivar,which was selected from the wild tara vine popula-tion growing at Dawei Mountain,Liuyang city,Hunan province.In early May of 2011,this single indi-vidual was propagated via cuttings or grafting,and cuttings were grafted on individuals of Actinidia de-liciosa collected from Dawei Mountain.After 6-year field trial,clones of this individual showed stable performance for all horticultural attributes.The tree vigor is moderate and most new shoots grow out in spring.These new shoots are purple red with dense white lenticels distributing on the surface.Newly formed leaves are yellowish green with red tips.Mature leaves are dark green with red petioles and ovate blades with serrated edges.The inflorescence is dichasium.The long columnar berry shows green skin and flesh just after harvest.Berry skin becomes purplish red after storage and berry flesh near seeds is purplish-red.Berry skin is smooth and covered with fruit wax.The berry shape index is 1.37,the average berry weight is 25.18 g,and the maximum berry weight is 28.33 g.Soluble solids content of berry is 13.13%at just harvest time.The total acid content is 1.13%,the soluble solids content could reach up to 26.50%after storage,and the average soluble solids content is 23.34%and the dry matter content is 22.28%.The average seed number is about 130 per berry.The vitamin C content is 36 mg per 100 g fresh weight,and the fruit stalk is 11.14-26.29 mm in length.The proper harvesting period is mid to late August,which is slightly earlier than early season and red-fleshed A.chinensis cultivar Hong-yang.This individual performs consistently and stably through six-consecutive-year field trial from 2017 to 2023.The individual is mainly propagated by asexual propagation methods such as hardwood cuttings,softwood cuttings and grafting.This desirable individual prefers growing environment with shading and cool climate.This new cultivar is suitable to be planted in areas with higher altitudes and relatively cool climate.Xiangmizao is mainly
