Pyrus-dwarf project: interim results

Abstract

The article presents the data based on 17 year-research – PYRUS DWARFT – aimed at developing varieties and complex donors of monogenously determined dwarfism (gene D), high winter hardiness, group-resistance to fungal diseases (Venturia pirina Aderh., Entomosporium maculatum Lev., Septoria piricola Desm.) and the bright red colour of a pear fruit (gene C). Their use in long-term innovative breeding technologies for obtaining pear varieties of the intensive type will allow screening at the early stages of ontogenesis and thereby reduce the number of hybrid families by 2–4 times. A brief description of complex donors is provided in the paper.
