Four tobacco varieties (three oriental and one semioriental) and their diallel hybrids from F1 generation were investigated during 1996 and 1997, in order to study the genotype components for inheritance of the characters: height of the stalk with inflorescence, number of leaves per stalk, length and width of the middle belt leaves and dry mass yield per stalk. The experimental design was a randomized block system with four replications. Manifestation of the characters investigated depends mainly on the additive genes (D>H1 and H2), with asymmetric distribution of their alleles (H2/4H1<0.25), except for the character dry mass yield per stalk, where H2/4H1=0.25, i.e. symmetrical allele distribution. The values for average level of domination show a partially dominant mode of inheritance of the characters (ÖH1/D<1). Interaction F for the characters number of leaves per stalk and length and width of the middle belt leaves has a positive value, and the ratio KD/KR>1, which indicates dominance of genes of the stronger parent. For the characters height of the stalk with inflorescence and dry mass yield per stalk, F is a negative value and KD/KR<1, i.e. in F1 progeny genes of the lower parent, with lower dry mass yield per stalk, are predominant.
