| 中文摘要: |
| “云锦1号”冰糖橙是西南大学柑橘研究所和云南省新平县农业农村局经作站从锦红冰糖橙中选育的果实呈长椭圆形的冰糖橙芽变优系。该品种单果质量160g，果形呈长椭圆形，果形比锦红冰糖橙更长，果基部具有短颈，果面橙色，果皮光滑，果肉浅橙色，可溶性固形物11.8 ,可滴定酸含量0.40%,保留了锦红冰糖橙高糖低酸、肉质脆嫩化渣的优点，糖度比锦红冰糖橙更高。在云南新平10月中旬成熟，比锦红冰糖橙早熟5~7天。采用SSR标记和S-SAP标记均证实“云锦1号”冰糖橙与锦红冰糖橙在DNA水平存在明显的遗传差异，具有遗传一致性、稳定性、和特异性。由于更高的糖度、更早的上市时间、独特的果形使得云锦1号作为优良冰糖橙选系开始在云南新平等甜橙产区进行推广发展。 |
| 英文摘要: |
| A new bud sport selection named Yun Jin No.1 derived from Jing Hong BingTang Orange were recently selected out from Xin Ping county, Yunnan province. The selection have oblong fruit shape and larger fruit shape index comparing with its parental line, the fruit is about 160g in weight and skin is smooth and orange in color, fresh is light orange and taste crisp and tender, the total soluble solids (TTS) is 11.8, titrable acidity is 0.4%, this selection keep elite traits of high sugar and low acidity flavor as it parental line but owned higher TTS, it ripened 5~7 days earlier than Jing Hong BingTang Orange in Xin Ping county. SSR and S-SAP analysis both showed apparently genetic difference between Yun Jing No.1 and its parental line. Higher TSS content, unique oblong fruit shapes and earlier ripen time made its an outstanding bud sport of BingTang Orange. As this new selection performed well in local place, it already grown widely in sweet orange producing area especially in Yunnan province. |
