Abstract
Five tobacco varieties, three of which oriental ( Prilep P-23, Macedonian Basma MB-3 and Yaka YK-48) and two semi-oriental (Forchheimer Ogrodowny FO and Otlia O-87) and their ten F1 hybrids were investigated for the characters: stalk height, leaf number per stalk and dry mass yield per stalk. The trial was set up in 2007-2008 on the field of Tobacco Institute - Prilep, in randomized blocks with four replications.
Subject of investigation was the inheritance of quantitative characters from parents and their combination in F1 progeny in order to obtain individuals which will satisfy the requirements and to create lines which will become stable in a short period of time.
The most frequent type of inheritance was partial dominance, which was followed by intermediate inheritance. Positive heterotic effect for stalk height was recorded in MB-3 x FO and in FO x O-87. No heterosis was detected for the characters leaf number and dry mass per stalk. The best GCA for stalk height and dry mass yield was obtained in FO variety, and for leaf number per stalk in P-23. SCA values were highly significant for stalk height and dry mass yield, and significant for leaf number. The best SCA was detected in hybrids MB-3 x FO, MB-3 x O-87 and P-23 x MB-3 for stalk height, in MB-3 x FO for leaf number and in MB-3 x YK-48 and YK-48 x FO for dry mass yield. MB-3, the variety with poor combining ability, was one of the parents in all perspective lines.
