摘　　要：‘豫榆1号’为自然选择品种,经多点多年对24个优良无性系进行选育研究,结果表明,‘豫榆1号’无性系在民权、孟州、孟津3个试点试验林的胸径、树高和材积均显著(P<0.05)高于对照‘65212’和其他白榆品种。在民权、孟州、孟津3个试点,‘豫榆1号’胸径分别超过对照17.43%、11.99%、19.30%;树高分别超过对照8.40%、7.67%、13.60%;材积分别超过对照52.61%、37.47%、57.56%;孟津试验林‘豫榆1号’较‘65212’胸径、高度、材积的增益均明显超过其他2个试点,与孟津试验点立地条件较好有关。Ulmus Pumilu‘Yuyu No.1’is a naturally selected variety.After multiple years of breeding research on 24 excellent clones,the results showed that the DBH,tree height and volume of Ulmus Pumilu‘Yuyu No.1’clones in Minquan,Mengzhou and Mengjin were significantly(P<0.05)higher than that of control'65212'and other white elm cultivars.In Minquan,Mengzhou and Mengjin,the DBH of Ulmus Pumilu‘Yuyu No.1’exceeded the control by 17.43%,11.99% and 19.30%,respectively.The tree height was 8.40%,7.67% and 13.60% higher than the control.The volume was 52.61%,37.47% and 57.56% higher than the control.The gain in DBH,height and volume of Mengjin test forest Ulmus Pumilu‘Yuyu No.1’was significantly higher than that of‘65212’,which was related to the better site conditions of Mengjin test site.
