能源型新品种‘豫刺槐3号’选育

Breeding of New Energy Type Variety Robinia Pseudoacaci Cl.‘Henan 3 for Forage’

选育抗逆适应性强、生物量大、抗虫易管的新能源良种是解决我国能源短缺问题、实现可持续绿色发展的重要途径。河南省林业科学研究院对收集的刺槐资源进行2级筛选,经多点区域化试验,选育出的‘豫刺槐3号’在平原沙区表现突出,单株生物量最大,7 a生单株生物量达46.23 kg,比‘豫刺槐1号’增益73.34%,在荥阳发展区比‘豫刺槐1号’增益25.94%,在洛宁发展区比‘豫刺槐1号’增益27.68%。该品种类型是一个很有发展前景的沙丘区能源型刺槐新品种,能在立地条件不好的沙丘区域良好地生长。‘豫刺槐3号’良种2015年通过河南省林木良种审定(编号:豫S-SV-RP-030-2015)。

It is an important way to solve the problem of energy shortage and realize sustainable green development by breeding new energy varieties with strong adaptability,large biomass,insect resistance and easy management.Henan Academy of Forestry conducted two-level screening on the collected Robinia pseudoacacia resources.Through multi-point regional test,Robinia pseudoacaci cl.‘Henan 3 for forage’showed outstanding performance in the plain sand area and its biomass per tree was largest.The biomass of 7-year-old single tree was 46.23 kg,which was 73.34%higher than that of the control,Robinia pseudoacacia CL.‘Henansis 1’.It was 25.94%higher than that of the control in Xingyang development area and 27.68%higher in Luoning.This variety is a new energy type with great development prospect in sand dune area,and can grow well with poor site conditions.It was approved by Henan Province in 2015(No.Yu s-sv-rp-030-2015).
