The article presents the results of research on potato culture, the presence of Ryadg,
Rysto, and Rychc genes in complex interspecific potato hybrids, and based on the use of the DNA
markers for selection of resistant forms to Potato virus Y (PVY). These genes are derived from
different genetic sources of the species Solanum andigenum, S. stoloniferum and S. chacoense,
respectively. The selected potato formswith a complex of agronomic characters are recommended
for inclusion in the selection process, for creation of new varieties, as well as as a valuable source
material for interspecific hybridization.
