The paper provides some guidelines on the choice of the target species compositions for plantations that would replace monocultural spruce stands growing on the sites of the Silesian Beskid Mts. Part of the guidelines relates to the rules governing the sequence in which the monocultures will be converted into mixed stands. It is suggested that those rules should be combined with the principles of the establishment of progenyplantations. The seed stands of the Istebna spruce are experimentally divided into four categories according to their abilityto perform the function of a seed stand. The following features of the stands are analysed: vitality, density, stage of regeneration, protective and cultural functions. The paper contains also an outline of the methods of species conversion and the relevant references.

In the present paper, the level of intra-population genetic diversity is described for 24 individuals belonging to the selected population of the Istebna region, in relation to the Polish Progeny Test. Using the RAPD-PCR technique, nineteen random primers were initially screened and seven, generating clear and polymorphic profiles, were selected. The intra-population genetic variation was low. The fact that the level of diversity did not exceed 0.041, showed a decrease of genetic variation of Istebna trees as compared to the genuine Norway spruce population from Central Europe. In the present study, the application of RAPD-PCR allowed the selection of a group of individuals characterized by a relatively higher level of genetic diversity.
