柑橘不育系新品种‘阳光1号’

‘Yangguang 1’–a New Monoembryonic Sterile Line of Citrus

‘阳光1号’(Citrus reticulata Blanco)是由‘红美人’(爱媛28)和‘春香’橘柚杂交而来的柑橘不育系新品种。树势强,坐果率高,叶面光滑,叶尖渐尖,果实呈高扁球形,大部分果实有短颈,果面光滑,易剥皮,果肉呈浅橙色,脆嫩化渣,无核,单果质量240~270 g,可溶性固形物为13.0%~15.0%,可滴定酸约为0.65%,维生素C含量435.0 mg·L^(-1)。重庆地区11月下旬成熟,耐贮运。露地栽培裂果率高,适宜于温室设施栽培。主产区在云南干热河谷地区、四川平原/丘陵地区、湖南湘西地区等,产量26.3~37.5 t·hm^(-2)。

‘Yangguang 1’(Citrus reticulata Blanco),developed by a crossing of‘Hongmeiren’(Ehime Kashi 28)as seed parent with‘Haruka’as pollen parent,is a monoembryonic and sterile line showing seedless and male-aborted.It is vigorous with high fruit-setting rate.The leaves have smooth surface with acute apex.The fruits are smooth and high flat-round in shape.The pulp is light orange in colour,crispy and tender.Single fruit weights 240–270 g in weight with 13.0%–15.0%total soluble solids,0.65%titratable acidity and 435.0 mg∙L^(-1) Vitamin C.In Chongqing,it matures in late November.The fruits are tolerant to storage and transportation,but tend to be suffered from high fruit cracking rate in the open field,so this cultivar is suitable for cultivation in greenhouse facilities.With annual yield of 26300–27500 kg∙hm^(-2),the major production regions include the dry-hot river valleys of Yunnan,plain/hilly area in Sichuan and western Hunan region.
