Abstract

Results are presented of investigations into oriental tobacco resistance to black shank disease caused by the pathogenic fungus Phytophthora parasitica var. nicotianqe. The investigations were carried out during 2007 in the biological laboratories of the Tobacco lnstitute-Prilep. Serious loss of tobacco yield and high application of chemicals in the control of this pathogen were key factors instigating the study and brought about the aim to obtain a healthier tobacco plant. The highest resistance among all species and varieties artificially infested with pathogen culture was noted in N. longiflora and N. plumbaginifolrc. Depending on virulence of the isolate, tobacco varieties reached various levels of resistance. The highest resistance was noted in variety Rila 82 in almost all isolates and variety Krumovgrad 58 was highly resistant to low virulent isolates.
