Plant Breeding and Acclimatization Institute - National Research Institute, Młochów Research Center

The Plant Breeding and Acclimatization Institute (IHAR) - National Research Institute (PIB) is the largest Polish research centre in the multi-disciplinary area of crop improvement, biotechnology, germplasm conservation and enhancement. IHAR was founded in 1951 for research in breeding and seed production of major field crops. Młochów Research Center is dedicated on the research on identification of genetic sources and the mechanisms of potato resistance to pathogens and abiotic stresses, enhancement of breeding for important agricultural traits, characterization and collection of Solanum plants and pathogens of potato.


The main research of IHAR related to the PVY research  team including: providing the PVY resistant breeding material to potato breeders, monitoring the PVY population changes in potato production, characterization of PVY resistance, studies on Virus –host interaction

Research topics covered:

  • Pre-breeding for PVY resistance
  • PVY population diversity in Poland
  • PVY strain identification and characterization
  • Antagonistic interactions between PVY  isolates in plants
  • Resistance genes to PVY - extreme resistance (ER) and hypersensitive resistance (HR).
  • Evaluation of PVY resistance of new potato cultivars
  • Proteomic comparison of potato genotypes with ER- and HR-mediated resistance to PVY
  • Host microRNA studies in potato-PVY, tobacco-PVY pathosystems
