In this paper, the morphological variability of autochthonous unregistered experi- mental white poplar clones, L-12, L-80 and L-100, and the registered reference clone Villafranca were monitored in a two-year nursery trial. The highest percentage of rooting of cuttings and survival of rooted cuttings were recorded for clone L-12, during the two growing seasons. The height of rooted cuttings of L-12 was almost identical to that of Villafranca during the first growing season (rooted cuttings 1/1), and slightly lower, in comparison to Villafranca, after the second growing season (rooted cuttings 1/2). The L-12 and Villafranca clones, which differed in diameter at 10th cm from shoot base, during both years, had the highest values of the diameter of rooted cuttings of both types. Coppicing appears to have an exceptionally positive effect on the increase in both height and diameter in clone L-100, while the production of quality rooted cuttings of L-80 requires further optimization.
