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. Other information about the project.
