摘　　要：通过苗期选择、测定及区域化栽培试验，从３７１ 个无性系中选育出５ 个速生、抗病、适宜培育工业用材的优良无性系，其生长速度、抗病能力、主效值、生产力指数等主要经济性状均明显超过对照；其树高、胸径遗传力、选择增益均高，效果显著，经环境互作及稳定性分析稳定性好，适应范围广泛。No 328,206,337,12 and 14 were selected from 371 clones by seedling selecting,clone test and regional test.The clones are suitable to produce timber for industrical use.Their economic properties like growth velocity,resistance to disease,main effect value and productivity index are obviously higher than these of the control.The heritability of height,DBH and selective agin are all high.They are proved to have good stability and wide adaptability by environmental intercropping and stability analysis and are worth popularising.
