The results of research on the production of raw timber assortments for the stands of poplar clones Robusta and I-214 in Slovakia are presented in this paper. Models of assortment yield tables were constructed, separately for each clone, in dependence on the yield class and stand age. The construction was based on the models of yield tables, stand assortment tables, models of external quality and damage to stems. Robusta clone produces by about 15–20% higher proportions of the highest quality assortments than I-214 clone. I-214 clone produces faster and higher proportions of average- and below-average quality assortments.Keywords:poplar clones; timber quality; assortment production; assortment yield tables
