摘　　要：仁选早柑是从贡柑田间优选单株中获得的早熟柑橘新品种。在韶关地区种植,11月上中旬成熟,较贡柑早熟近1个月。果实近球形,平均单果质量78.07 g,果形指数为0.84,果皮黄橙色,较易剥皮,囊瓣整齐,果肉中等橙色,脆嫩化渣。果实可溶性固形物含量(w,后同)为14.0%,维生素C含量(ρ)为356 mg·L^(-1),总酸含量为0.52%,总糖含量为11.2%。对黄龙病不具抗性,易感褐斑病。丰产性好,5年生树产量18750~37500 kg·hm^(-2)。Gonggan is a local characteristic mandarin variety in Guangdong with a cultivation history of over 1100 years and a total cultivation area of approximately 26667 m^(2).Breeding early maturing citrus varieties can solve the problem of inconsistent market quality caused by early harvest of citrus,and also avoid excessive concentration of market periods.In September 2017,Renxuanzaogan was found in an orchard where Gonggan was cultivated,in Renhua County,Shaoguan city by the Fruit Research Institute of the Guangdong Academy of Agricultural Sciences,Shaoguan University,Shaoguan Agricultural Science and Technology Extension Center,and Renhua County Agricultural and Rural Development Service Center.After three consecutive years of observation on biological characteristics,it was proved that its maturity period was one month earlier than the control Gonggan,with significant and stable differences existing.The certificate of Plant New Variety Rights was issued by the Ministry of Agriculture and Rural Affairs in 2023(CNA20201005931).As is similar to the control variety Gonggan,this variety is susceptible to citrus huanglongbing and citrus brown spot disease.The tree posture of Renxuanzaogan is open.The spring shoots have short spines,with a length of 0.10 cm.The leaf blade is broadly lanceolate,with wavy edges,leaf shape index of 2.07,petiole length of 0.85 cm,and narrow winged leaves.The flower is white with 5 petals,1.32 cm in length and 0.59 cm in width,and 13-16 filaments,partially united.The anthers are light yellow,and the style is arched,higher than the stamens.The fruit is nearly spherical,with a single fruit weight of 78.07 g and a fruit shape index of 0.84.The fruit surface is glossy,with flat oil cells.The fruit skin is yellow orange,with a thickness of 0.15 cm,which is easy to peel off.The core is semi-plump,and the segments are semi-lunar and neat.The segment membrane is thin and easy to separate,and the juice sacs are compact and spindle-shaped.The flesh color is uniform,with a medium orange color.The fruit e
