Interspecific and intraspecific diversity on resistance to Y virus in potato

The specimens of cultivated and wild species of potato from collection of N.I. Vavilov Institute of Plant Industry (VIR) were estimated on their resistance to Y virus with the use of phytopathological and molecular-genetic methods. The authors revealed the inter- and intraspecific variability on their resistance to Y virus and also the diversity of plant’s response in cultivated and wild species of potato on viral infection. Several samples of potato genotypes with available diagnostic components RYSC3-320 and GP122-EcoRV-406 are selected and characterized on their resistance to potato virus Y, which are the source of forms, valuable for breeding.
