The aim of the paper was to study the mode of inheritance of the characters stalk height, leaf number per stalk, middle belt leaf area and green/dry mass yield per stalk in F1 and F2 progenies of four tobacco varieties (Prilep P12-2/1, Pobeda P-2, Yaka JV 125/3 and Forchheimer Ogrodowny - FO). The trial was set up in 2006 at the field of Tobacco Institute-Prilep in randomized block system with four replications. Narrow-sense heritability was estimated using Allard’s formula (1960), and broad-sense heritability by Mather and Jinks’s formula (1974).
These investigations can be used in selection of parental pairs to obtain new varieties.
The highest value for narrow-sense heritability in F1 was obtained for the character middle belt leaf area. Broad-sense heritability in F1 and F2 was highest for the character green mass yield per stalk. Leaf number per stalk had the lowest values for both narrow- and broad-sense heritability and in both generations.
Higher heritability values in both narrow and broad sense indicate the presence of high genetic and low ecological variance, which makes the quantity characters highly inheritable and it means that future generations will be fixed and stabilized.
