| ‘瑞阳’是西北农林科技大学由‘秦冠’作母本，‘富士’作父本杂交选育而成的晚熟苹果新品种，2018年春季，天水市果树研究所通过国家现代苹果产业体系引进该品种进行栽植，并对植物学特征、果实主要经济性状、生长结果特性、物候期以及抗冻性与抗病性等进行观测分析，总结其栽培技术要点。该品种平均单果重261.5 g，最大果重331.6 g，果形指数0.85，果实圆锥形，果面鲜红色，全面着色，果点较平、小、中多，果面蜡质中多，果粉薄，果面光洁，果顶微有棱，果肉黄白色，细脆、多汁，风味甜，具香味；可滴定酸含量0.32%，可溶性固形物含量16.1%，去皮硬度7.32 kg/cm2，果实10月中下旬成熟，贮藏性好；11月下旬树体落叶，树势中庸健壮，树姿半开张，栽植第4年667 m2产量1769.6 kg；第5年667 m2产量2396.8 kg；该品种具有早果丰产、品质优良、适应性强、管理容易等优良特征，可作为黄土高原产区苹果更新换代无袋栽培的主要品种。 |
| 英文摘要: |
| ‘Ruiyang’ is a new late-ripening apple variety produced by Northwest A&F University with ‘Qin Guan’ as the Maternal parent and ‘Fuji’ as the Paternal parent. In the spring of 2018, The Tianshui Fruit Research Institute introduced this apple variety through the National Modern Apple Industry System and conducted cultivation trials, observed and analyzed its botanical characteristics, key fruit economic traits, growth and fruiting habits, phenological phases, as well as frost resistance and disease resistance. Based on these studies, key cultivation techniques were summarized. ‘Qin Guan’ with an average weight of 261.5 g and a maximum weight of 331.6 g. The conical-shaped fruits index of 0.85, bright red skin with complete coloration. The skin texture is smooth and glossy, characterized by small, flat lenticels of moderate density, a medium wax coating, and a thin natural bloom. A slight ridging is observed at the fruit's apex.The yellowish-white flesh is fine-textured, crisp, and juicy, offering a sweet flavor with a pleasant aroma. Analytical measurements show a titratable acidity of 0.32%, soluble solids content of 16.1%, and a peeled fruit hardness of 7.32 kg/cm2. The fruits reach maturity in mid-to-late October and demonstrate excellent storage potential.The trees exhibit moderate yet vigorous growth with a semi-open canopy structure, typically shedding leaves in late November. Yield performance reaches 1769.6 kg per 667 m2 in the fourth year after planting and increases to 2396.8 kg per 667 m2 in the fifth year. Notable for its early fruiting, high productivity, and superior fruit quality, this variety demonstrates strong adaptability and ease of management. These outstanding characteristics make it an ideal candidate as a next-generation, bag-free cultivation variety for apple production in the Loess Plateau region. |
