QUANTITATIVE-PHYSICAL TRAITS OF SEMI-ORIENTAL TOBACCO VARIETIES AND LINES

Through continuous scientific work and a tradition of 100 years, Scientific Tobacco Institute- Prilep has preserved and developed a large number of oriental, semi-oriental, and large-leaf tobacco varieties. In the Department of Genetics, selection, and seed control, semi-oriental tobacco varieties have been created and preserved, and they remain promising despite the fact that the purchase of this tobacco type is not legally regulated. In the 2018 harvest, a trial was set up using the Randomized block system method in 4 repetitions with 3 semi-oriental varieties: O 9-18/2 (Ø), O 110-88/3, and O. Zlatovrv, and 3 newly created lines: Maya-96, Maya-94, and Maya-CMS. Examined semi-oriental tobacco varieties and lines belong to the group of additional types of tobacco characterized by good quantitative and characteristic physical properties. The leaves of the newly created varieties are characterized by a lower percentage of veins, with the lowest percentage found in line Maya-94 (20.09%). They also have a characteristic leaf thickness for this tobacco type. Our goal was to present certain quantitative and physical properties of the tested semi-oriental tobacco varieties and lines that could successfully be included in cigarette blends. The obtained results show a convincing dominance of variety O. Zlatovrv and lines Maya-96 and Maya-94 over the other varieties included in the study.
