Genotypes and interspecific hybrids of potato (Solanum tuberosum) in varieties collection were analyzed in the conditions of the Republic of Belarus. In course of the study there were analyzed the Solanum samples revealing resistant to common scab which was caused by eight species of Streptomyces: S. scabies, S. griseus, S. globisporus, S. violaceus, S. candidus, S. chromofuscus, S. violaceoruber, S. melanospofaciens. Among wild species and interspecific hybrids in the in vitro culture there were selected high-resistant forms by the analyzed parameter. Research results showed that 18 samples of South American wild varieties and 22 samples of 10 North American wild varieties showed common scab resistance measured up to 7 points and higher.
