Potato (Solanum tuberosum) is the one of the most important cultivars in belarussian agriculture. Its intensive cultivation is the way of food shortage decline. But the problem of disease and pest protection continue to be the most actual. Nowadays in Belarus there are no anti-nematode preparations, effectively protecting potato from stem nematode (Ditylenchus destructor Thorne). Crop rotation and culling of tubers reduce significantly the losses caused by stem nematode; however they don't minimize its harmfulness. The most important method of control over stem nematode is cultivation of resistant or weakly affected varieties breeding of which is linked to a number of additional difficulties connected with accumulation of invasion material and creation of artificial invasion conditions. For the purpose of reproduction and accumulation of invasion D. destructor as nutritious substrates there are studied various species of fungi which can be food reserves for nematode in soil. The methods of the estimation are developed and the breeding material of potato is estimated in respect of susceptibility to stem nematode. The initial material for breeding of the varieties resistant to D. destructor is identified.
