The paper presents the results of evaluating the growth and health of 20 different poplars from the Aigeiros group in 30-year populetum Leles on uninundated alluvia of the Latorica River in ecological conditions of the lowland Východoslovenská nížina. The populetum is situated on medium-heavy loamy soils in the group of forest site types Ulmeto-Fraxinetum carpineum. The results of evaluation document that out of the investigated poplar clones the poplars I-214, I-476, Blanc du Poitou, Flachslanden and P. nigra (Baka 5) had the best height and diameter growth and maximum volume production. Their health status was also very good. The lowest volume production was determined in P. nigra (009/66 ČR), I-455 and Grandis, and the worst health was found out in Grandis, P. nigra (Pavlovce 1) and P. nigra (Ivachnova 1). These results will facilitate to include the poplars I-476 and Flachslanden in the assortment of regionalized poplars for the lowland area of Východoslovenská nížina.Keywords:
