摘要
本文介绍了连续两年用11个优良种源的155个自由授粉家系为材料进行的种源—家系配合试验的结果。它表明优良种源区家系间存在明显的差异,为陕西3种地类分别选出可供生产利用的10个优良家系,树高遗传增益达12%～18%。
The paper introduced the coordination experiment results on white Elm provenance and family,which are carried on the 155 open pollination materials from 11 superior provenances for two year's study. The result shows that the significant differences existed among the superior provenance families,the fine families were selected for 3 kind of site types,the genetic gains of tree height are 12%～18%.
