Were studied the inheritance, coefficient of hereditability and of the teams, the number of the genes and the manifestations of transgression and heterosis in terms of length and width of the upper leaves of harvesting belt in Burley tobacco. For this purpose studied populations P1, P2, F1 and F2 seven hybrid combinations. The data from the hybridological analysis showed that samples tested our Burley tobacco, inheritance of the length of the upper leaves of harvesting belt is overdominantly or additive, and the width overdominantly or semidominantly. It is estimated that heterosis and transgression appear reliable way to increase the width of the upper leaf harvesting belt in the selection of Burley tobacco. There is very small number and minor variations in genes influencing the trait determine the size of the upper leaf harvesting belt. Is verified low values for the coefficient of heritability, which is why the team signs a length and width of the sheet 19 to 20 will be effective in later hybrid generations.
