Abstract
Aim of this paper was to investigate heredity of plant height, number of leaves per plant, middle zone leaf area, green mass yield and dry matter yield per plant in F1 and F2 progeny of four tobacco varieties: Prilep – P12-2/1, Pobeda – P-2, Jaka –YV125/3 and Forchheimer Ogrodowny – FO. In F1 progeny the highest narrow-sense heritability value was estimated for dry matter yield per plant while in F2 progeny was for middle zone leaf area. In both investigated generations the highest broad-sense heritability value was estimated for green mass yield per plant, while the lowest narrow and broad-sense heritability was estimated for number of leaves per plant.
