Summary: The genetic methods are used to improve mean values of thecharacter which is selscted in a given population by thevegetative or generative reproduction of the selected part of thepopulation in the following forest tree species: the white willow(Salix alba), the black alder (Alnus glutinosa), the silver birch(Betula pendula), the common oak (Quercus robur) and the blackpine (Pinus nigra). Furthermore, the genetic differentiation oflocal populations of the said species is studied in order toimprove, on the basis of the determined genetic diversities, seedproduction and seedling nursery production and to proceed withthe genofund preservation of these species by using "ex situ" and"in situ" methods.

Keywords: forest tree improvement, Salix alba, Alnus glutinosa, Betula pendula, Quercus robur, Pinus nigra, clone, half sib progeny, full sib progeny, provenance, genotype x environment interaction, phenotypic and genotypic variability.

Research goals: As for arborescent willows, the objective of researches is to select such clones which will meet various requirements and purposes: the multiclonal approach in classical plantations with a high trunk production and quality; the efficient growing, even in atypical willow stands such as, for instance, various types of oak stands in lowland forest regions, in the function of an easier regeneration of the more valuable species of deciduous trees (the common oak, the ash); the exuberant growth in the ontogenetic early stage with a good shooting power from stumps (biomass, energy forest plantations), the production of new horticultural forms to meet requirement of the horticulture. For the black alder, the silver birch and the common oak, the objective is to determine the intrapopulation and interpopulation variability as an essential prerequisite for the improved breeding of the said species in terms of seed production and seedling nursery production. By means of black pine race and family tests, to determine the optimal races and families for the formation of plantations in the submediterranean region as well as in the continental climate area, on various types of degraded soils.
