Resistance to Pathogens of the Potato Accessions from the Collection of N. I. Vavilov Institute of Plant Industry (VIR)
In total, 154 accessions of wild potato species from VIR’s potato collection were screened at IHAR-PIB Młochów Research Center (Poland) for resistance to Phytophthora infestans and, a part of them,…

MOLECULAR SCREENING OF POTATO VARIETIES BRED IN THE NORTHWESTERN ZONE OF THE RUSSIAN FEDERАTION
TLDR
The information about the presence of markers of R genes and about cytoplasm types of hybrids and varieties will allow an effective implementation of further breeding programs for resistance to a complex of pathogens, including pyramiding of R genes.

Resistance to Phytophthora infestans and Potato virus X (PVX) in wild potato species Solanum acaule Bitt. from the collection of N. I. Vavilov Research Institute of Plant Industry.
Wild potato species from the VIR collection as source of resistance to late blight.
Phenotypic characteristics of North-West Russian populations of Phytophthora infestans (2003-2008) [Conference poster].
TLDR
Frequencies of Phytophthora infestans genes for virulence had been examined for the samples collected in North-West region of russia in 2003-2008 and it was detected that the mean numbers for the virulence genes per isolate increased from 7.7 in 2003 to 8.1 in 2008.
