Hypericum perforatum L.; RAPD markers

Sažetak
Population structure in a Hypericum perforatum L., hybrid apomictic plant species of medicinal importance, have been studied using RAPD markers. Total of 109 samples collected from 8 various locations in Croatia were compared on the basis of RAPD profiles obtained by amplifications with six primers. The results obtained show gene diversity in H. perforatum L. in range between 0, 121 and 0, 301. Three populations have significantly lower level of diversity: Adriatic populations from Solin and Knin (0, 121 and 0, 188) as well as Pannonic from Kutjevo (0, 188). Four populations, two from Istra (Učka 0, 246 and Funtana 0, 262) and two from middle Croatia (Plitvice 0, 269 and Baške oštarije 0, 263), have similar diversity, while population from Kalnik has higher level of diversity (0, 301). Higher polymorphism of one population as well as variations in values between different populations may be explained by residual fertility and outcrossing which may has occurred in some populations. High fixation index (0, 331) indicates limited gene flow as the consequence of prevaling apomixis.
