【Abstract】 Longfan No.8 is a new hybrid developed by crossing 920354 with 920387.Fruit is oblate and pink. Average fruit weight is 138.7g. It takes only 45 days from flowering to first harvest and maturity is 9-10 days earlier than that of Xifen No.3. Early yield 2.52t·hm -2 is 18.3% higher than that of Xifen No.3 and occupied 38.26% of total yield. It is suitable for cultivation in Beijing,Shijiazhuang,Zhengzhou,Lanzhou,Urumqi and Hefei.更多还原
