摘要
本文通过对１８个杨树品种无性系在９个试验点的Ｇ×Ｅ互作分析，用８个参数评价生产力，遗传稳定性和生长适应性，并经综合评定，从村冠积比（材积／冠积）方面将１８个品系划分为不同类型，为各试验区评选出了适合栽培的优良品系。
in this paper 18 poplar clones were analsed using 8 parameters.Their hereditary stability and growing adaptability have been evaluated. By comprehensive evaluation from the valume ratio of trunk to crown the 18 poplar clones have been divided into different types and the suitable clones have been selected for each experiment region according to their charateres.
