Sažetak
In the work the multivariaty analysis of the common oak leaf samples (Quercus robur L.) has been made in an attempt to get a better picture of the individua1 and populational variability of the common oak in Croatia. The ana1ysis comprised in total 20 common oak populations originating from various bioclimatic regions (Posavina and Podravina, plus four control populations from Istria, Slovenia and Germany). By the analysis significant differences between populations have been found out, the differences between trees inside a population being greater than those between the popu1ations. Such results 1ead to the conclusion that each population has approximately the same number of genotypes and that the difference occurs only in the survival (presence, frequency), that is very likely in close connection with ecological factors (edaphic and climatic). The research relating to the common oak variability in the territory of the Republic of Croatia is in the function of acquiring better knowledge of the local population genetic differentiation as an essentia1 basis for separating the seed stands (i.e. dividing the seed stands into areas) and for preserving the common oak genetic reSOlJrce.
