Abstract

The structure of C. parasitica populations was evaluated in Štiavnicko-krupinská subpopulation in Slovakia. A total of four vegetative-compatibility (vc) types were detected among the sample of 215 isolates, which respond to following European vc types: EU-12, EU-2, EU-13, and EU-8. Number of vc types on single sites varied between one and four. One vc type (EU-12) was the dominant in Štiavnicko-krupinská subpopulation. This vc type (EU-12) comprised 93% of all isolates and was found on each site. Two vc types were represented by only one or two isolates. The observed vc type frequencies were compared with expected vc type frequencies. The χ2 test showed that the observed vc type frequencies differed significantly from the frequencies expected under random mating.
