Abstract: Severe apple proliferation (AP) epidemics are spread in the most important apple growing areas in Europe with a significant economic impact on the production of marketable fruits. A genotype screening was undertaken on 41 apple cultivars and selections showing no phytoplasma-related symptoms to identify natural resistance or tolerance to `Candidatus Phytoplasma mali'. Among the tested cultivars or selections most of asymptomatic trees of cultivars Brina and Enova resulted to be positive to phytoplasma presence, while in selection CO-OP12 only one out of 34 tested plants resulted positive to AP infection.
