study of cryphonectria parasitica polymorphism - causative agent of chestnut blightin northwestern caucasus
Abstract
In this study, we give mycological analysis of bark samples of Castanea sativa from
Russian part of its habitat. We isolated 97 strains of phytopathogenic fungus Cryphonectria parasitica
in pure cultures, among them one hypovirulent strain containing CHV virus was identified. We
studied vegetative compatibility of those strains and showed the threat of Cryphonectria parasitica
impact on Russian population of chestnut.
