N2 - Recent results of the conventional apple breeding programme at the Institute of Fruit Breeding Dresden-Pillnitz show new multiple disease resistant cultivars, which possess a high fruit quality and productivity and resistance against economically important diseases, e.g. fire blight caused by Erwinia amylovora, and abiotic factors. The objective is breeding of fire blight resistant cultivars, combined with resistance to scab, mildew, bacterial canker, red spider mite, and winter and spring frosts by conventional breeding methods. Donors with high fruit quality and yield, e.g. 'Cox Orange', 'Elstar', 'Golden Delicious', 'James Grieve', 'Pilot', 'Pinova', 'Pirella' were combined with fire blight resistant donors, e.g. Pi-A-44,14, Pi-AS-181, 'Reanda', 'Rebella', 'Regia', 'Remo', 'Rewena' or 'Enterprise' by crossing. The fire blight resistant cultivars transmit their high degree of resistance into their progenies. The resistance of cultivars, hybrids and wild species has been evaluated by inoculating growing shoots in the greenhouse and blossoms in the field since 1972. New fire blight resistant cultivars with different degrees of resistance to scab, mildew and partially to other diseases and abiotic damage are 'Reanda', 'Rebella', 'Regia', 'Remo', 'Resi', and 'Rewena'. They also possess a high stable level of fire blight resistance under natural infection conditions. These cultivars have high fruit quality and high productivity values combined with multiple resistances to fungal and bacterial diseases. They were released and are growing in commercial orchards.
