摘　　要：云青1号是云南省红河热带农业科学研究所科研人员从云南省河口县集市上购买柚果后通过种子繁育选育出的柚新品种。该品种树势强旺,树姿开张,萌芽力中等,成枝能力强;果实呈饱满长水滴形,平均单果质量1.56 kg,果实可食率68%,可溶性固形物含量(w,后同)11.3%,总酸含量0.47 g·100 g^(-1),固酸比24.04,维生素C含量56.7 mg·100 g^(-1),维生素E含量0.407 mg·100 g^(-1)。在云南省河口县2月初现蕾,3月盛花,9月下旬成熟,果实生育期190 d左右。果实成熟后,果面主色绿色,果肉红色,汁胞呈水晶切面晶莹剔透,无苦麻味,汁胞不粒化,单一品种种植表现为无籽或少籽。该品种植株较耐贫瘠,耐高温高湿,适宜热区栽培,云南南部热区和全省低热河谷区域均可种植。Yunqing 1 is a new pomelo cultivar selected by Honghe Tropical Agricultural Science Institute of Yunnan.In September 2007,the researchers purchased a batch of pomelo with green skin and red pulp from the market of Hekou county,Honghe Prefecture,Yunnan province.Finally,104 maternal trees were obtained through seedling breeding.Those trees began to bear fruit in 2013.After two consecutive years of observation,an optimized strain with early flowering,medium ripening,large fruit juice content,high sweetness,long fruit retention time and resistance to granulation of flesh was selected.In 2014,local sour pomelo was used as the rootstock for top-grafting and the observation experiment was conducted.In 2016,the flower and fruit were tested.After two consecutive years of investigation on the botanical characteristics of the top-worked Qingpi red pomelo,no atypical plant appeared in the investigation.In 2018,the application for protection of new varieties was submitted to the Ministry of Agriculture and Rural Affairs.After years of continuous observation,the variety performance was stable in Hekou of Yunnan province.In October 2021,it passed the on-site examination of experts.On March 7,2023,it was authorized by the Ministry of Agriculture and Rural Affairs for the protection of new varieties of plants(Code of Plant variety rights:CNA20184826.0)and named Yunqing 1.The cultivar has strong growth vigor,open tree gesture,medium bud breaking rate and strong branching ability.It enjoys sunlight and high temperature environment.It begins to produce in third year,and enters the fertile period in fifth year.The fruit shows long water droplet shape.The average weight of single mature fruit is 1.56 kg and the edible rate of fruit is 68%.The soluble solid content is 11.3%,the total acid is 0.47 g·100 g^(-1),the solid/acid ratio is 24.04,the content of vitamin C is 56.7 mg·100 g^(-1),and the content of vitamin E is 0.407 mg·100 g^(-1),all of which were superior to the control variety Chandler pomelo.In Hekou area of Yunnan,the bud
