Abstract

Results of investigations on oriental tobacco resistance to black shank disease caused by the pathogenic fungus Phytophthora parasitica var. nicotianae are presented in this paper. Investigations were carried out during 2007, in biolab of the Tobacco Institute-Prilep. The main reason to initiate the investigations were the serious loss of tobacco yield and high application of chemicals in the control of this pathogen, with an aim to obtain a healthy tobacco plant. The highest resistance among all species and varieties artificially infested with pathogen culture was noted in N. longiflora and N. plumbaginifolia. Depending on virulence of the isolate, tobacco varieties reached various level of resistance. The highest resistance was noted in variety Rila 82 in almost all isolates, and variety Krumovgrad 58 was highly resistant to the low virulent isolates.
