Poplar () clones are widely used for riparian afforestation owing to their fast growth and ecological benefits. However, selecting suitable clones for site-specific conditions remains a key challenge. In this study, we evaluated the survival and growth performance of nine poplar clones belonging to three hybrid groups- (D), × (DN), and × (NS)-at two riparian sites in Korea. Significant differences were observed in the survival, height, diameter, basal area, and basal area increment (BAI) among clones and between sites. DN hybrids exhibited superior overall performance in both survival and growth traits compared to D and NS clones. In the DN group, clones Eco-28, I-476, and Dorskamp consistently ranked highest in aggregate performance. Notably, I-476 and Eco-28 demonstrated both high productivity and stability across sites, as reflected in their low coefficients of variation (CVs). In contrast, Dorskamp, while highly productive, showed relatively high variability across environments. These findings highlight DN hybrids-particularly Eco-28 and I-476-as promising candidates for riparian afforestation, offering a balanced combination of high productivity and environmental stability.
杨树（）无性系因其生长迅速和具有生态效益而被广泛用于河岸造林。然而，为特定立地条件选择合适的无性系仍然是一项关键挑战。在本研究中，我们评估了属于三个杂交组——（D）、×（DN）和×（NS）——的九个杨树无性系在韩国两个河岸地点的存活和生长表现。在无性系之间以及地点之间，观察到存活、树高、胸径、断面积和断面积生长量（BAI）存在显著差异。与D和NS无性系相比，DN杂交种在存活和生长性状方面均表现出卓越的整体性能。在DN组中，无性系Eco - 28、I - 476和多施坎普在综合性能方面始终排名最高。值得注意的是，I - 476和Eco - 28在各地点均表现出高生产力和稳定性，这体现在它们较低的变异系数（CVs）上。相比之下，多施坎普虽然生产力很高，但在不同环境中表现出相对较高的变异性。这些发现突出了DN杂交种——特别是Eco - 28和I - 476——作为河岸造林有前景的候选品种，它们兼具高生产力和环境稳定性的平衡组合。
