Project summary:

The potato is one of the most important crops worldwide. The annual potato harvest in Poland is estimated at 8 700 000 tons, while 321 100 tons were produced in Norway in 2010. Climate change has a significant impact on agriculture today, especially on plant pathogens. The project will focus on the two important pathogens of potato:  late blight and soft rot of tubers. Chemical protection against late blight is expensive and has a negative impact for the natural environment. However, for bacterial diseases there are no chemical and biological methods of protection, therefore the only solution is production of disease–free seeds.The aim of the project is to gain knowledge on interactions between host, pathogen and environment in order to reduce the cost of protection against late blight and minimize losses caused by Pectobacterium spp., Dickeya spp. and Phytophthora infestans.The specific objectives are:

  • Characterization of present populations of late blight and pectinolytic bacteria in Norway and Poland,
  • Evaluation of resistance of different potato genotypes to selected isolates of pathogen,
  • Identification of inoculum source and sensitivity to diseases in regard to the weather,
  • Development of methods for identification and detection of bacteria in seed potato,
  • Development of system predicting late blight appearance infection based on weather.
