Dalmatian sage (Salvia officinalis L.) is a perennial subshrub growing in rocky habitats and represents one of the most significant autochthonous species in flora of eastern Adriatic coast and islands. Genetic diversity and population structure of 23 populations from Croatia and two from Bosnia and Herzegovina were analyzed using eight microsatellite markers. The majority of populations were in Hardy-Weinberg equilibrium while significant deficit of heterozygotes was detected in six populations. Southern populations showed the highest values of gene diversity and allelic richness which gradually decreased towards north. Values of genetic differentiation were low indicating high levels of gene flow. Analysis of molecular variance showed that most of total genetic diversity was attributable to within population variation. Bayesian analyses of population structure revealed the existence of riverine barriers in the northeast-southwest direction (Zrmanja, Cetina), as well as mountain ranges (Velebit, Biokovo) in the direction of northwest-southeast. A significant pattern of isolation by distance was observed. There was no clear indication of recent genetic bottlenecks.
