Abstract

ABSTRACT Macedonian tobacco production is recognizable around the world by oriental types of tobacco, represented by a large number of varieties. The morphological properties of tobacco are a very important factor in determining primarily the type of tobacco, and then the individual varieties within the species. These traits of each species or variety are more or less different and are genetically controlled. Experience to date in this area shows that tobacco plants of a certain type under the influence of agro-ecological conditions and agro-technical measures in vegetation can also show strong variations in terms of bio-morphological properties, especially leaf dimensions. Important indicators for determining the quality of raw tobacco are: insertion, leaf size, content, elasticity, color, degree of damage. Therefore, the aim of the study was to present the characteristics of Basma’s varieties from the middle belt insertion: length, width and angle of attachment to the lower middle, right middle and upper middle leaf, in the stage of technological maturity. The study was conducted in the field of the Tobacco Institute in Prilep; the trial was set up in 5 replications, using a random block system, including 4 oriental varieties of tobacco: three Basma’s: MK-1, MB-2 and MB-3, and Yaka 7-4/2 as a control (ø). Basma’s varieties were created by the Scientific Institute for Tobacco - Prilep, and the State Commission for Variety Recognition recognized them in 2010. The obtained data were statistically processed and tested by LSD test. In terms of leaf dimensions, the length of the lower middle leaf for the MB-3 variety showed statistically significant differences compared to the control variant. On average, all Basma’s varieties have slightly larger leaf dimensions compared to Yaka 7-4/2 (ø), but the dimensions of the middle belt leaves (MB-3), are important for achieving higher green mass yield per plant/per hectare and obtaining quality raw tobacco.
