At the Institute for Fruit Growing in Belarus historically, much attention is paid to fruit breeding, particularly to apple and pear. The basis for the creation of the Belarusian varieties of new generation is National apple (1,264 accessions) and pear (660 accessions) collections, which host a selection of new sources of germplasm for the most important breeding traits. During 2011-2013 are formed target characters collections for disease resistance: for apple - resistant to scab and powdery mildew - 42 genotypes, for pear - resistant to scab and septoria – 25 genotypes. The work’s collection are presented by biodiversity: 7 progenies of Gr. Sorbomalus, 5 – Gr. Baccatae, 4 – Gr. Prunifolia, 20 – Gr. Domesticae for apple and 5 – Pyrus communis, 10 – P.ussuriensis, 9 – P.pyrifolia, 1 - P.ussuriensis × P.pyrifolia for pear. New Belarusian target collections for resistance to diseases are content genetic diversity and advance to development of commercial varieties with the long-term, stable resistance to major diseases.
