Abstract

A new method for early selection of wild cherry clones for resistance to Phytophthora sp. is presented. Four Phytophthora species (P. cinnamomi, P. citrophthora, P. megasperma, P. alni) were tested in vitro on four micropropagated cherry (Prunus avium L.) clones obtaining reliable and reproducible results. Variability in clone susceptibility and in pathogen virulence was shown. P. citrophthora was confirmed to be a dangerous pathogen owing to its capability to induce symptoms quickly and to its fitness in the Mediterranean climate. On the contrary P. alni did not result to be a dangerous pathogen for wild cherry
