摘　　要：白城地区可选择的蒙古黄榆优良无性系为向海保护区的022、024、025、037、039、043、044,河北省丰宁县的丰1、丰2、丰3,黑龙江省防护林研究所的防4。表现较好的无性系遗传增益为树高5 8%,胸径11 9%,干形2 2%。优良无性系单位面积蓄积比实生林提高36 8%。Studies on elite clones selection of Ulmus macrocarpa var. mongolica indicate that: № 0.22,№0.24,№0.25,№0.37,№0.39, №0.43 and №0.44 of Xianghai National Nature Reserve of Jilin, are all growing well in Baicheng region of China; In Hebei province, №1,№2,№3 of Fengning County are better than others; and №4 of Institute of Protection Forest of Heilongjiang Province is more suitable for there. Among these clones, some genetic gains could reach in 5.8% of the tree height, 11.9% of the DBH and 2.2% of the form; the volume ratio by area raised 36.8% compared with seedling stand.
