摘　　要：为了寻找最佳母树,筛选出速生型黄榆优良家系,本文采集不同地点的黄榆种子进行播种育苗试验。结果表明:松花湖三年生黄榆平均苗高124.4~246.7cm,小白山三年生黄榆平均苗高105.6~151.2 cm,东团山三年生黄榆平均苗高126.4~219.5 cm,永吉县黄榆乡三年生黄榆平均苗高104.1~156.7 cm;S5为最佳采种地母树编号,即将松花湖5号母树列为培育速生型黄榆优良家系的采种母树。In order to find the best mother tree and screen out the fast-growing genotype superior family of Ulmus macrocarpa,this paper collected Ulmus macrocarpa seeds from different locations for sowing and seedling experiments.The results showed that the average seedling height of the three-year-old Ulmus macrocarpa in Songhua Lake was 124.4-246.7 cm,that of the three-year-old Ulmus macrocarpa in Xiaobai Mountain was 105.6-151.2 cm,that of the three-yearold Ulmus macrocarpa in Dongtuan Mountainwas 126.4-219.5cm,that of the three-year-oldUlmus macrocarpa inHuangyu Township of Yongji County was 104.1-156.7 cm.S5 was the mother tree number of the best seed collection site,namely,No.5 mother tree in Songhua Lake was listed as the mother tree for cultivating the fast-growing genotype superior family of Ulmus macrocarpa.
