Sažetak
Immortelle (Helichrysum italicum /Roth/ G.Don) is a perennial thermophilous subshrub widely distributed in the Mediterranean basin. Immortelle essential oil is highly praised having a wide range of remarkable medicinal properties. In recent years, massive uncontrolled commercial exploitation of wild immortelle populations prompt the Ministry of Environmental and Nature Protection of the R. of Croatia to limit or even ban wild harvesting. Genetic diversity and population structure of 18 immortelle populations from Croatia were examined by using amplified fragment length polymorphism (AFLP) markers. By assuming that the populations were in Hardy- Weinberg equilibrium, Wright's index of genetic differentiation was significant but low suggesting extensive gene flow among populations. The analysis of molecular variance indicated that the most of the genetic diversity was attributable to differences among individuals within populations in concordance with the patterns expected for an outcrossing and moderately long-lived species. Bayesian Analysis of Population Structure (BAPS) resulted in assignment of the investigated samples in two clusters. Samples originating from populations sampled in northern Adriatic were assigned to Cluster A, while the Cluster B included the samples belonging to populations from the middle and southern Adriatic. The results were compared with those obtained from AFLP analyses of Dalmatian sage (Salvia officinalis L.) and Dalmatian pyrethrum (Tanacetum cinerariifolium Trevir. /Sch./ Bip.) populations from Croatia in which the similar pattern of genetic diversity and population structure has been observed.
