  • Disease resistance testing to potato wart disease.

Resistance to S. endobioticum is important to maintain crop health. Growers need reliable information about resistances, to different pathotypes of S. endobioticum, when they have to choose a variety. Laboratory of Quarantine Organisms runs different types of tests, according to European and Mediterranean Plant Protection Organization (EPPO) standards, and keeps the most relevant pathotypes od S. endobioticum and potato cultivars of differential set.

For some specific crops, information about resistance to different pathotypes of S. endobioticum must be included in the variety description that is required to define and protect a variety. The official tests are curried out using the Glynne-Lemmerzahl method, according to EPPO Standard PM 7/28 published by the European and Mediterranean Plant Protection Organization. For resistant cultivars of potato to different pathotypes of S. endobioticum an appropriate Certificates of resistance are issued.

Inoculation of potato sprouts using The Glynne-Lemmerzahl method.
Reaction of susceptible potato genotype to pathotype 1(D1) 4 weeks after inoculation.
  • Monitoring and identification ofS. endobioticum isolates.

Individual isolates of S. endobioticum may be able to overcome specific resistances. It is therefore useful to define pathotypes based on their reaction to a range of well-characterized differential cultivars. Pathotests are curried out using the Glynne-Lemmerzahl method, according to EPPO Standard PM 7/28, on at least 20 differential cultivars of potato (if it necessary) to include less known pathotypes.

Different reaction of cv. Asche Sämling to pathotype 3(M1) and 2(Ch1) of S. endobioticum.
  • Collection of S. endobioticum pathotypes and isolates >

Laboratory has an pathotype and isolate collection of S. endobioticum. The collection is used for resistance testing in connection with cultivar registration trials. Different pathotypes and the isolates are validated regularly through biotests on differentiating resistant cultivars. The collection contains the most relevant pathotypes of S. endobioticum from Western Europe : 1(D1), 2(G1), 6(O1), 8(F1), 18(T1); from Poland: 2(Ch1), 3(M1), 39(P1) as well as the isolates from The United Kingdom, Sweden, Bulgaria, Denmark, Greece and Poland.

  • Monitoring of Globodera rostochiensis and G. pallida population changes in Poland. Identification of PCN pathotypes in soil samples.

  • Collection and maintance of five pathotypes of golden potato cyst nematodes (G. rostochiensis Ro1-Ro5) and three pathotypes of white potato cyst nematodes (G. pallida Pa1-Pa3).
  • Assessment of resistance of potato variety and breeding lines to G. rostochiensis (Ro1-Ro5) and G. pallida (Pa1-Pa3) pathotypes.
  • Detection of Ralstonia solanacearum in potato tubers, waste water and solid wastes.

  • Detection and diversity of Clavibacter michiganensis subsp. sepedonicusisolates using molecular techniques.

Clavibacter michiganensis subsp. sepedonicus causes a dangerous bacterial disease called ring rot of potato. The disease is of quarantine status in the EU as a result of losses it causes easiness of its spread. It means, this disease is controlled by national regulations and there is zero tolerance for this pathogen in the potato crops. This bacterium generates a huge threat for seed material and breeding production and hinders trading of potato in the EU and other countries. Lack of sufficiently sensitive methods of detection and identification is the reason for poor elimination of this pathogen.
