Abstract: Bulgarian oriental tobaccos are characterized by high content, distinct smoking feature and finesse, and are one of the most sought-after tobaccos in cigarette manufacturing. The purpose of the research is to make a chemical assessment, based on which to determine the smoking qualities of varieties and lines of oriental tobaccos from the Dupnitsa ecotype. The yield, class percentage, chemical composition and smoking qualities of Line 503 (high nicotine selection) and Line 504 (low nicotine selection) were investigated. The obtained results were compared with established high-quality varieties - Dupnitsa 160, Katerini and Rila 544 (control). It was established that the studied lines had a higher yield than the control and a quality corresponding to Dupnitsa 160 and Katerini varieties. The chemical composition of the new lines is consistent with typical oriental tobacco values for nicotine, sugars and total nitrogen. The selection lines have a balanced chemical composition and good smoking qualities.
