Opis:: The study aimed at estimating the genotype × environment (G × E) interaction, stability and plasticity parameters for height growth and survival of hybrid aspen (Populus tremula L. × Populus tremuloides Michx.) clones. A set of 17 hybrid aspen clones were studied at age four in 11 field trials (series 1) and a set of 12 clones were studied at age 12 in three field trials (series 2) in Sweden, Finland and north-west Russia. There was an intermediate and significant correlation between height ranks at four and 12 years, showing modest G × E interaction for tree height. The corresponding correlation for survival was weak and insignificant, indicating a stronger G × E interaction than for height. The stability parameter (S) for height showed large differences among clones. The plasticity index (PI) values for height ranged from 0.6 to 0.8 among clones, demonstrating high levels of phenotypic plasticity.

Opis:: This research was carried out on two experimental plots located in the Rymanów and Nawojowa forest districts. In the second and fifth year after planting, at three and six years of age respectively, survival and height of 25 beech progenies of selected stands were measured. Furthermore, we show the effect of beech origin and growth environment (significant ‘provenance × block’ and ‘provenance × test plot’ interactions). Beeches from both experimental plots differed significantly in growth and survival and this difference increased with tree age. The highest provenance heritability was obtained for the tree height after two years of growth in Rymanów. In Nawojowa, the heritability of beech survival reached zero after five years of growth. An evaluation of the stability of beech provenances (genotypes) in terms of survival and height under the habitat conditions of our experimental plots was done using the Finlay and Wilkinson method. The beech provenances of 469–Nawojowa and 452–Lesko (regional standard) were included as a stable basis for reference. A high degree of stability and high average values for the characteristics investigated indicate highprogeny quality within these stands.
