摘要
‘锦秀’是从普通冰糖橙芽变中选育出的冰糖橙新品种。果实扁圆,果面橙色,果面光滑,果肉浅橙色,果实平均纵径62.99 mm,横径72.33 mm,果形指数为1.08,单果质量188 g,果皮厚5.57 mm,每果实含种子0.2粒,出汁率64.52%,可溶性固形物含量(w,后同)为12.0%,总糖含量10.89%,可滴定酸含量0.2%,固酸比60,维生素C含量(ρ)为58.08 mg·100 mL^(-1),可食率为76.53%。果实生育期210 d,在湖南省麻阳县11月下旬成熟。抗寒、抗旱和抗病性与普通冰糖橙类似。采用SSR标记对‘锦秀’的遗传鉴定表明,其与普通冰糖橙在DNA水平存在差异,具有遗传特异性。适合全国甜橙优势栽培区和其他甜橙种植区。
‘Jinxiu’is a new sweet orange variety selected from bud mutation of common Bingtang Orange plants in Hongjiang county.It was initially selected in 2007 for its low acid,soft flesh and high juice in Mayang county.To further observe the propagation and characteristics of the cultivar,in 2008,the cultivars were grafted and propagated in their progeny,and using 2-year-old seedlings of Poncirus trifoliata Raf.with similar diameter as rootstock.To evaluate regional adaptability,the new variety was tested respectively at five sites,such as:Pinlin village,Changtanxi village,Tongziliang village,Xiangyang village and Tongyoupo village,from 2009 to 2015.Through years of investigation on botanical/biological characteristics and fruit quality during the citrus bearing seasons,it was showed that genetic traits of‘Jinxiu’with high grafting had good genetic stability and fruit quality.Finally,in 2015,it was selected as the common Bingtang Orange excellent bud variant variety for promotion and has applied for and obtained the protection of new plant varieties,as well as the registration of non-major crops.The‘Jinxiu’tree growth potential is strong,tree appearance opens,branch density is big.The average spring leaf length,leaf width,and leaf shape index is 69.8 mm,34 mm and 2.1,respectively;the length and width of autumn tip leaf is 89 mm and 54 mm,the leaf shape index is 1.6.The fruit is flat and round with no mastoid process at the top,then with a smooth orange color peel.The longitudinal diameter and transverse diameter of the fruit are 62.99 mm and 72.33 mm respectively.The weight of single fruit is 188g and the thickness of the peel is 5.57 mm.Also,the flesh is orange,the core is full,and the sacs are neat.According to fruit quality test,it has 0.2 seed per fruit,76.53%edible rate,64.52%juice yield,12.0%TSS,0.20%TA,and 58.08 mg·mL^(-1) vitamin C.In Mayang county,the fruit ripening period of‘Jinxiu’was about 210 d,and the varieties entered the germination stage in March and the flowering stage in April,physiol
