‘东丰龙眼’(品种审定之前称‘东莞二号’)是以‘储良’龙眼为母本,父本(可能是‘石硖’龙眼或广西‘大乌圆’龙眼)杂交而成的新品种。经DNA指纹分析,其真正的父本是‘石硖’龙眼。其主要优异性状为:1)品质上等。味清甜,爽脆,可溶性固形物为20.1%,果肉乳白色,不透明,表面不流汁;2)果大。平均单果质量10.2 g,比‘石硖’大,比‘储良’略小,可食率为69.4%;3)丰产稳产。产量高且稳产,其丰产稳产特性比‘石硖’的还要好;4)‘东丰’粗生快长,叶片大,生长势强,抗逆性强。‘东丰’龙眼于2012年1月通过广东省农作物品种审定委员会审定(粤审果2012001)。
’Dongfeng Longan’ (before the approval of varieties, ’Dongguan No.2’) is a cross between ’Long’ and ’Long’, and its male parent (possibly ’Shilong Longan’ or Guangxi ’Big Oolong’ Longan) New varieties. The DNA fingerprinting analysis, its real father is ’stone 硖’ longan. The main excellent traits are: 1) high quality. Taste sweet, crisp, soluble solids 20.1%, pulp milky white, opaque, the surface does not flow juice; 2) large fruit. The average fruit weight is 10.2 g, which is larger than that of ’Shijie’ and slightly smaller than that of ’Chu Liang’. The edible rate is 69.4%. 3) High and stable yield. High yield and stable yield, and its high yield and stable yield properties are better than those of ’Shijie’; 4) ’Dongfeng’ is thick, long and fast with large leaves, strong growth potential and strong resistance. ’Dongfeng’ longan in January 2012 by the Guangdong Provincial Crop Variety Approval Committee (Guangdong audit 2012001).
