Abstract

Four oriental varieties (Prilep P-23; Djebel Dj No 1; Smirna; YK 7-4/2), two semi-oriental (Otlia O-87; Floria Fl-breeding line) and their fifteen diallel F1 crosses were investigated for the characters: stalk height with inflorescence, number of leaves per stalk and dry mass yield per stalk. Crossings were made during 2002, and the experiment was set up in 2003 in Tobacco Institute-Prilep, with randomized block system in three replications. Mode of inheritance of the characters was determined on the basis of test-significance of obtained mean values from F1 progeny, in relation to the average of parents. Analysis of combining abilities was made by Griffing (1956). The investigations revealed high values for GCA (general combining abilities) in all three characters, which indicates dominance of additive genes in their inheritance. The best GCA for stalk height was found in FL and the worst in P-23. There were six crosses with highly significant values for SCA (specific combining abilities), the best among which was Dj No 1 x Fl. The best GCA for the character number of leaves per stalk was noticed in P-23 and the lowest in Dj No 1. The crosses with the best SCA (Dj No 1 x FL and Dj No 1 x Smirna) reached significant values. The best GCA for the character dry mass yield per stalk was recorded in FL and O-87, and the worst in the varieties Smirna and Dj No 1. Highly significant values for SCA were found in Dj No 1 x YK 7-4/2, YK 7-4/2 x FL and Dj No 1 x Smirna. The study will be used in breeding parental pairs for successful combining of certain positive characters, which can find practical application in selection of perspective lines and their stabilization in as short time period as possible.
