Investigations were made on the inheritance of some morphological (height of the stalk without inflorescence and leaf number per stalk) and agronomic characters (green/dry mass yield per stalk) in oriental tobacco varieties Prilep (P 12-2/1), Djebel (Pobeda P-2), Yaka (YV 125/3) and semioriental Forchheimer Ogrodowny - FO, with their six F1 and six F2 hybrids. Crossings were made in 2004 and 2005, and the final trial with parents and hybrids was set up in 2006, in the field of Tobacco Institute-Prilep, at randomized block system with four replications.
The aim of investigations was, through regression analysis, to give complete picture of the genetic system for inheritance of the above mentioned characters.
Values of the major genetic components for graphic presentation were calculated from the average values of characters, using the methods of Mather and Jinks (1974).
The regression analysis reveals partially dominant mode of inheritance and lack of integral interaction. In variety P 12-2/1, according to the position of dots along the regression line, dominant genes are prevailing in the inheritance of morphological characters, and additive genes in the inheritance of agronomic characters. In P-2 variety, dominant genes are prevailing in the inheritance of stalk height and additive genes for all other characters YV 125/3 possesses both dominant and additive genes, with small changes in their prevalence. In FO, recessive genes mainly prevail for inheritance of height stalk and dominant genes for the other characters. Exception is the dry mass yield in F2 generation, where additive genes are prevaling.
