Chestnut blight in Croatia and Slovenia

Cryphonectria parasitica, the filamentous ascomycete responsible for chestnut blight, has been devastating chestnut trees in Croatia and Slovenia for sixty years. In order to improve knowledge of its diversity, 338 isolates of the fungus from ten Croatian populations and 254 isolates from eleven Slovenian populations were sampled. Eighteen vegetative compatibility (vc) types were identified in Croatia and fifteen vc types in Slovenia. The vc type EU-1 was the most widespread in Croatia, followed by EU-2 and EU-12, while EU-13 was the dominant vc type in Slovenia, followed by EU-1, EU-2 and EU-12. Vc type diversity in the most diverse Slovenian population was higher than diversity of previously characterized populations in northern Italy and Croatia. Despite the high diversity of vc types, hypovirulent isolates were detected in all Croatian populations and in six out of seven tested Slovenian populations. The highest incidence of hypovirulent isolates was observed in continental part of Croatia, while hypovirulence was low in the coastal part of the country. In Slovenia, the highest percentage of white isolates was found in the population sampled near the Croatian border and the lowest in the population near the Austrian border. All identified hypoviral isolates from Croatia and Slovenia belonged to the subtype I of the Cryphonectria hypovirus 1 (CHV-1) and were closely related to the viruses previously found in other European countries.
