Sažetak
Dalmatian sage (Salvia officinalis L.) and Greek sage (S. fruticosa Mill.) are two closely related species. In Croatia, the island of Vis is the only known locality where these two species grow sympatrically. Dalmatian sage is naturally widespread in Croatia, whereas the origin of Greek sage in this location is probably related with the ancient Greek colony. Besides sharing same habitat on the island, these two species have same chromosome number (2n=14) as well as the same flowering time. All these features together with the facts that plant breeders managed to produce their commercial hybrid, that botanists reported morphologically intermediate individuals in the wild and that several microsatellite loci identified for S. officinalis were successfully amplified in S. fruticosa, encouraged us to study putative natural hybridization events on the island of Vis using microsatellite markers. A total of 79 plant samples were analyzed (16 individuals of S. officinalis, 38 of S. fruticosa and 25 of intermediate hybrids). Hybrid origin of morphologically intermediate individuals has been genetically strongly supported. Microsatellite genotyping showed that the putative hybrids possessed alleles in common with the proposed parental species and intermediate values of genetic differentiation. Evolutionary, conservation and commercial implications of this hybridization were discussed.
