| Abstract:
The aim of the Pillnitz apple breeding programme was to develop both good fruit quality and high yield. All clones with high susceptibility to scab and mildew were eliminated in field evaluations. This programme developed the "Pi-series" ("Pi"- = Pillnitz) of apple cultivars: 'Piros', 'Pinova', 'Pilot', ‘Pirol’, ‘Pia’, ‘Pingo’ and others. Later the cultivar 'Steinantonovka' was used as a polygenic scab resistant source, and Malus floribunda and other wild species with different resistance sources were also involved. The results are the cultivars of the "Re-series" ("Re"- = Resistance). Fungicides can be reduced by at least 80 % in growing of these cultivars which have good fruit quality, early and high cropping and demonstrate resistance to scab and to some extent to other fungal and bacterial dieseases. | |
