Sažetak
A diallel cross of four cigar and one pipe tobacco was analysed for the following characters: (1) height before topping (2) heigh after topping (3) number of leaves (4) leaf width (5 leaf lenght (6) leaf angle and (7) days from transplanting to flower. The experiment was performed over three years with four replications. Analysis was done for general combining ability and specific combining ability. General combining ability was in all cases greater than specific combining ability, although there were some specific combining effects. The line Pennbel 69 showed very high positive general combining abilities for all characters while the line Petit Havane showed negative general combining abilities for thesecharacters. Commercial production of F1 hybrids would not seem to be of any advantage for any of these characters with these parental lines.
