In the conditions of the Republic of Belarus there was realized an evaluation of influence of infestation terms on potato (Solanum tuberosum) varieties resistance to black leg disease (disease agents: Pectobacterium carotovorum subsp. Carotovorum; and Pectobacterium caratovotum subsp. atrocepticum) at storage period. Potato varieties were artificially infected at storage. Potato plants were inoculated by a mix of strains agents: P. carotovorum subsp. carotovorum and P. caratovotum subsp. atrocepticum. Research results showed that for the obtaining of the most reliable figures on potato tubers resistance to black leg it was necessary to realize the artificial infection infestation at a storage period from the third decade of January till the third decade of March. There was marked the dependence of the value points of potato resistance to black leg on the weather conditions at vegetation period.
