The resistance of apple tree cultivars (Malus domestica Borkh.) towards different pests and diseases is relevant for the today breeding programmes. In this respect it is important to access genetic resources from gene banks as well as from traditional apple pools. In Romania such orchards are not very often today but certain remains from the XVIII century can be found especially in Transylvania. The scope of this article is to present the incidence of infestation with apple powdery mildew (i.e. Podosphaera leucotricha) for 24 old apple varieties found in Fântânele, Sibiu County. Among the 937 investigated apple specimens, in four different landscape subunits for a three consecutive years (i.e. 2014, 2015, and 2016) three varieties proved to be extremely sensitive (i.e. Golden delicious’ 'Grosse Casseler Reinette’ and 'Jonathan’). On contrary local varieties proved to be resistant. Also 'Boiken’, London Pepping’, 'Edelborsdorfer’, 'Reinette Ananas’, 'Gustav’, 'Astrachan Rouge’ , and 'Red Delicious’ proved to resist to the attack of apple powdery mildew.
