High population diversity of Cryphonectria parasitica in Croatia might hinder natural biological control of chestnut blight

Vegetative compatibility types of Croatian C. parasitica isolates were determined, microsatellite loci analysis was performed and genetic diversity indexes estimated. Eighteen different vc types and 37 microsatellite haplotypes were observed with EU-12 found in eastern, and EU-1 and EU-2 predominantly in western and coastal populations. GST estimates and ANOSIM support the observation that Croatian C. parasitica populations combine features of both western and south-eastern European populations. Sexual fruiting bodies (perithecia) were observed and both mating types in 1:1 ratio were found, suggesting that sexual reproduction of the fungus is common which results in recombination and new vc types expansion, thus preventing unobstructed dissemination of CHV1. Multilocus linkage disequilibrium index also supports the hypothesis of predominant sexual reproduction. Although hypovirulence has been present in Croatia for a long time, and hypovirulent strains of fungus have been observed in most Croatian chestnut populations, sexual reproduction of C. parasitica and diversification of fungal populations might halt transmission of CHV1 and natural biological control of the disease. This problem deserves attention especially in the coastal region of the country where the incidence of hypovirulence is low and human-mediated biocontrol is needed.
