COMPOSITION AND UTILIZATION OF THE APPLE- TREE COLLECTION IN BELARUS

The national collection of apple-tree varieties consisting of 1,273 accessions was used to develop genetically diverse source material developed involving progenies of wild small-fruit apple species (Sorbomalus, Baccatae and Prunifolia) - sources and donors of immunity to scab and powdery mildew.

Description
Summary:The national collection of apple-tree varieties consisting of 1,273 accessions was used to develop genetically diverse source material developed involving progenies of wild small-fruit apple species (Sorbomalus, Baccatae and Prunifolia) - sources and donors of immunity to scab and powdery mildew. A new trait-specific working collection of fungal disease resistance sources and donors has been established. Using molecular markers made it possible to identify large-fruit donors with 2-3 oligogenes of apple scab resistance in the same genome, and small-fruit donors with 1-3 oligogenes of powdery mildew resistance. New late-ripening apple-tree cultivars Belana, Diyament, Zorka, Krasavita, Navavita and Sakavita with high scab resistance and high fruit quality have been developed.
