Possibility of seed usage of pedunculate oak (Quercus robur L.) in Bosnia and Herzegovina on the basis of its genetic structure

In the analysis of genetic variability and differentiation of the pedunculate oak population (Quercus robur L.) we used 14 natural populations evenly spread across Bosnia and Herzegovina, with the total of 255 analyzed trees, using four highly polymorphous micro-satellite loci (micro-satellite markers: ssrQpZAG1/5, ssrQpZAG9, ssrQpZAG36, and ssrQpZAG108). This research provided the value of inter-population differentiation of FST = 0, 089 of the total genetic diversity, with large diversity within the populations with the value of FIS = 0, 225, i.e., large polymorphism. Based on the above stated, we can draw a conclusion that there are differences among examined populations of the pedunculate oak. Differences in genetic differentiation were maybe caused by different processes of the post-glacial migration—for example, maybe the ability of some gene types to adapt to certain habitats with specifi c selection processes, and probably also anthropogenic impacts over the past 2, 000 years. Since we did not obtain population groups on the basis of genetic similarities, even when climatic factors were included in the calculation, all populations are separate entities and we can have seeds and seedlings from the seed base at our disposal, but with the great risk of genetic contamination of local populations.
