摘  要:
The variations among populations within species for Populus ussuriensis arevery rich. The study on population selection in its whole distribution regionhas been conducted for selecting best population which can be used in forest-ation directly. Firstly, the main economic characters of Populus ussuriensispopulations collected form 9 places of origin, such as growth, rooting ability,cold and rust resistance have been determined in Daxinganling, then evaluatingthese economic characters comprehensively, finally the best population has beenselected.
