ABSTRACT
During the last years the major target of our apple breeding programme to diseases resistance were scab resistance as well as multiple resistance to powdery mildew and fire blight. The first promising result we received from Liberty, Generos, Florina and Dayton – o.p., i.e. between 75.0-50.0% scab resistant seedlings and between 31.2% to 41.2% mildew resistant ones. The resistance from German cultivars Renora, Reanda, Rebela and Rewena - o.p. were also very high, that is between 53.3 – 72.5% scab resistant. The progenies from Generos x Reglindis and Generos x Remo were 57.89 and 78.05% resistant seedlings to Erwiniaamylovora Burr., respectively.
