摘　　要：砂糖灯笼橘是由传统砂糖橘芽变单株选育而成的新品种。果面橙红色,表面凹凸有致,纹络分布均匀,果实呈扁球形,极易剥皮。平均单果质量41.60 g,果形指数0.69,无籽。果肉甜脆爽口,水分足,极化渣,可溶性固形物含量(w,后同)为13.80%,总酸含量为0.39%,总糖含量为10.80 g·100 g^(-1),维生素C含量为30.30 mg·100 g^(-1),可食率为69.40%。叶片有轻度扭曲,呈斑驳状绿化,叶偏小,有浅绿深绿两种颜色,叶片不对称。在广西梧州成熟期为12月初,早结丰产稳产,植株抗病性很强,极易管理。采用SSR分子标记对砂糖灯笼橘遗传鉴定表明,砂糖灯笼橘与传统砂糖橘在DNA水平上存在差异,品种区试生物学特性观察结果证明,该品种具备稳定性、一致性、特异性。砂糖灯笼橘适合我国砂糖橘产区栽培,成熟期较砂糖橘提前25 d。Shatang Lantern tangerine,a novel Citrus reticulata Blanco cultivar,selected from bud sport of Shatang tangerine.This cultivar showcased robust tree posture,vigorous growth,abundant branch-ing,prolific flowering,and efficient fruit setting.The average weight of fruit was 41.60 g.The fruit was flattened spherical in shape with a transverse diameter of 43.64 mm,longitudinal diameter of 30.31 mm,and a fruit shape index of 0.69.The fruit peel was orange-red in color and easy to peel.The soluble solid content(w)was 13.80%,the total sugar content of 10.80 g·100 g^(-1),the total acid content was 0.39%and the vitamin C content was 30.30 mg·100 g^(-1).Shatang Lantern tangerine ripeped 25 days ear-lier than the common Shatang tangerine.Genetic analysis using SSR markers revealed discernible DNA-level distinctions between Shatang Lantern tangerine and common Shatang tangerine.
