摘要
本试验以马尾松(Pinus massoniana)高产脂种子园20个优良家系为研究对象,开展不同家系在6个月培育期内的千粒重、发芽率、生物量、苗高和地径生长性状差异性及相关性分析。结果表明,不同家系各项生长指标存在极显著差异,选育潜力很大,综合选择16号、20号、9号和6号为较优家系。
This test used 20 excellent families selected from high-yield seed orchard of Pinus massoniana L.as the research object to conduct the differences and correlation analysis on growth traits of different families in 6 months of planting period,including 1000-seed weight,germination rate,biomass,seedling height and ground diameter.The results showed that there were highly significant differences in the growth traits among different families,showing great potential of breeding,and the families of No.16,No.20,No.9 and No.6 were optimal for a comprehensive selection.
