The diseases Phytophthor a crown and root rot consist of the most important problems in cherry cultivation. In this study, the susceptibility of 30 cherry genotypes to Phytophthora cactorum , P. citrophthora, P. parasitica and P. citricola was evaluated by using excised twig assay, excised shoot method and stem inoculation method. The results showed that all cherry genotypes tested were susceptible to all Phytophthora isolates used. Phytophthora parasitica and P. citrophthora were the most aggressive species. Host specificity of the Phytophthora isolates used in this study was not found although these isolates were from different plant species. In conclusion, because none of the cherry genotype showed a level of resistance to these pathogens, caution should be taken when these genotypes are used in locations, where these diseases are endemic.
