The study in Belarus the most dangerous and quarantine fungus Synchytrium endobioticum (Schilb.) Perc. – potato wart disease agent has shown that the resistance feature is obligatory and ecologically safe method of losses decrease from the disease. The necessity of immunological evaluation of potato breeding material for wart disease resistance is substantiated. Among the potato hybrid material studied for resistance to the (D1) pathotype of wart disease agent from the breeding institutions of Belarus and Russia for the period of 2003-2007 in preliminary first year testing there were 83,9% of resistant samples, the second year -92,4%, in State testing -91.9%. By immunological evaluation for wart disease resistance it is very important to observe conditions favourable for the interaction of a fungus parasite and a host plant. It is determined that the parasitic fungus activity and the susceptible plants reaction on infection becomes weaker by potato planting at later than recommended time
