Investigations were carried out with five old domestic oriental tobaccos of the types: Prilep (P 10–3/2 and P 12–2/1), Djebel (Dj №1) and Yaka (YK 7–4/2 and KY)and five commercial oriental varieties of Prilep tobacco (P–23, P–84, NS–72, P–66–9/7 and P–79–94), to study the number, length, width and area of the middle belt leaves per stalk. The trial was set up inthe Experimental field of Tobacco Institute–Prilep in 2013 and 2014, in randomized block design with three replications, using traditional agricultural practices. The aim of the investigation is to study some autochthonous varieties and new commercial varieties for the stated quantitative traits, and with analysis of variance to estimate the significance of differences by varieties and years, which will improve our knowledge on stability of the traits, genotypical homogeneity and progress in selection of oriental tobacco in the Republic of Macedonia. Differences in leaf the number and size among genotypes in the two-year investigations are highly significant, which is genetic indicator of their mutual differences. The error of the mean value is low, indicating stability and homozygosity of the genotypes. The variety P–66– 9/7 is characterized with the highest number of leaves (x= 60) and it has 33 leaves more than YK 7– 4/2 and Dj №1. The largest leaf size was measured in P–79–94 (x= 23,3cm – length, 12,1 cm – width, 179 cm2–area). It has 4,8 cm longer, 3,2 cm wider and 74,5 cm2 larger leaves then YK 7–4/2, which is characterized by the smallest leaves. These data point out to a successful breeding activity of the Tobacco Institute in the selection of oriental aromatic tobaccos. Through evaluation of stability of varieties, the breeder improves its knowledge ontheir homozygosity and higher security in the choice of parental pairs for implementing selection programs.
