At the ripe stage, its skin and flesh are yellow and yellowish green, respectively. The fruit kernel is long and pointed at both ends. Compared with the control variety Xiangzhong, the fruit shape is quite different. The shape is egg shape and the top shape is round. The surface, base, and top of the fruit have no radial lines. Its skin is yellow too. The Lingjian Ganlan average fruit weight is 8.84 g. The longitudinal diameter and transverse diameter of fruit is 3.61 cm and 2.33 cm, respectively, and the fruit shape index is 1.55. The flesh is thick and the thickness is 0.56 cm, the edible rate is 83.7%. The total soluble solid and crude fiber is 12.3% and 3.4%, respective-ly, the total sugar is 4.3 g per 100 g, the vitamin C is 18.9 mg per 100 g, the titrating acid is 9.65 g·kg^-1,the content of tannin is 9.06×103 mg·kg^-1 and the content of calcium is 842 mg·kg^-1. Obvious, LingjianGanlan is larger than the local variety of Xiangzhong, with bigger fruit, thicker flesh, and higher edible rate. The contents of vitamin C and total soluble solid are high, but the titrating acid, crude fiber and tan-nin contents are low. And it tastes sweet and refreshing, with light astringent. It has a strong branching ability, and can be planted in ChaoShan area of Guangdong province. The adult trees shoot 3-4 times from March to December every year, usually sprouting in mid-March, and the spring shoots stop growing to become fruiting shoots in mid-May. The flowering period is short, about 3 to 4 days. The first flowering period is the Mid-May, the full flowering period is the end of May, and the final flowering pe-riod is the early of June. The fruit growth period is about 190-210 days, and the ripening period is in the mid and late of December, later than the local variety of Xiangzhong. Under the same conditions, the av-erage yield per 666.7 m² of adult trees of Lingjian and Xiangzhong reached 647.5 kg and 422.5 kg, re-spectively, showing high and stable yield characteristics. In general, Lingjian Ganlan is suitable for planting in Chao-Shan area of Guangdong, the grafted plants can blossom and bear fruit in the third year, indicating that it has a broad market prospect Ganlan.
