摘　　要：引进１９个欧美杨无性系进行苗期测定，估算了群体各性状广义遗传力等遗传参数，经综合评价，初选出９１０—１４０、２５４—５５、９１６—２１０、Ｗ１—２９四个优良无性系，其遗传增益苗高为７．６５％、胸径为１１．２９％、材积为２６．１２％。clones of european american poplar were introduced for seedling measurement.Four good clones of 910-140,254-55,916-210,W 1-29 were primarily selected through cousprehensive evaluation.Heredity gains of them are 7.65%,11.29% and 26.12% for height,diameter and volume respectively.
