| Abstract:
The present results of classic apple breeding show new multiple resistant cultivars, which possess a high fruit quality and productivity and are highly resistant against the most important diseases and damaging factors in the Central European climatic region. The main breeding aim for resistance is multiple resistance and its stability. The most important fruit, tree and resistance characteristics can be combined by classic methods. Donors are available which transmit these different characteristics well. With classic breeding programmes, new efficient cultivars were developed, which are suitable for modern fruit production. The best example is the new multiple resistant cultivar ‘Rebella’, which was released for cultivation in 1998. ‚Rebella‘ has attractive fruits, a high fruit quality and yield and also multiple resistance against scab, mildew, fire blight, bacterial canker, red spider mite, winter frost and spring frosts. The cultivars ‘Regine’, ‘Remo’, ‘Rewena’ and ‘Reglindis’ carry also 6 or 5 different resistances, combined with high fruit quality and productivity. These multiple resistant cultivars can be the new base of breeding progress to increase the degree of the stable disease resistance in a long term programme. Apple breeding will continue to be successful in the future if classic breeding methods will combined with new molecular methods. | |
