Abstract
The aim of this study was to investigate the mode of inheritance of leaf number per stalk, area of the middle belt leaves and yield of dry leaf mass per stalk in four F1 tobacco hybrids. These tobacco hybrids were obtained by crossing five varieties, four of which are Oriental in the role of mother and one Broadleaf as a father. Investigations were made in 2020 and 2021. The most common mode of inheritance is negative dominance for the first trait, partial for the second trait and intermediate dominance for the third trait. There is no heterosis. The best results considering the size of the middle belt leaves and the yield of dry mass gave P-76/86 x B-1/91. The obtained mode of inheritance is an indicator of good selection of individuals in future generations and quick fixation and stabilization of the traits. The four hybrid combinations represent very interesting starting material for tobacco breeding.
