Summary
The preservation of durable resistance to scab is important for the practical cultivation of new scab resistant varieties. New results were observed in different years and in a range of locations in connection with the breakdown of scab resistance derived from Malus floribunda (Vf). Several scab resistant selections were attacked by scab infections, but preserve their resistance as ‘field resistance’. They showed only weakly susceptible reactions (classification 3b) in one or two years without influence on yield and fruit quality. The most durable resistance was observed with a combination of genes from several resistance sources (Vf × Vr, Vf × VA, Vr × VA). The best planting strategy is to mix varieties with resistance from different genetic sources.
