摘要

‘Dianyinhua 3’is bred through the selection of a good single variant plant based on Hunan Lonicerae Flos variety‘Xianglei 1’as the basic material.The scions of the variant plant were grafted and propagated with wild Lonicera macranthoides Hand.-Mazz.as rootstocks.This variety belongs to L.macaroides,which has the characteristics of early flowering,large and numerous buds,concentrated flowering and abundant yield.The content of chlorogenic acid is as high as 6%,and the content of luteolin is 0.017%.It matures from late May to early June in Yunnan.The buds are rod-shaped,slightly curved,4.6-5.8 cm long,with a diameter of 6.47 mm at the top and 2.68 mm at the bottom,and the petals have a thickness of 0.33 mm.The thousand-flower bud weight was 15.8-18.2 g,and the average yield of dried flowers per plant was 1360-1680 g in the peak period,and the yield was 4887 kg/hm^2.It is suitable for the introduction and trial planting in Xiangyang Mountainous Area or rocky desertification mountainous area in Yunnan,with an altitude lower than 2200 m or in areas with similar climates such as Sichuan,Guizhou and Guangxi.
