Abstract

Investigations included 9 oriental tobacco cultivars in a role of father, representing the types Prilep (P 12-2/1, P-84, PV 156/1, P-23 and P-7), Yaka (YV 125/3 and YK -23) and Djebel (Dj No 1 and Pobeda P-2); 2 semioriental varieties in a role of mother (Otlia O-87 and Forcheimer OgrodowniFO) and their 18 F1 hybrids. The investigated characters were: height of the stalk with inflorescence, number of leaves per stalk, length and width of middle belt leaves and their relative area. Crossings were made in the course of 2002. The experiment was set up in 2003, on the field of Tobacco Institute-Prilep in a randomized block with three replications. Measurings were made in the beginning of flowering. Based on the average values obtained, standard deviation, parents and hybrids variability and the way of inheritance of investigated characters were estimated. Investigations revealed the existence of significant differences between parents and their F1 hybrids. Cultivars and their hybrid progenies apppeared to be highly uniform. The inheritance of stalk height is intermediary and partially dominant, except for the hybrids O-87 x P-84 and FO x Dj No 1, which showed dominance of the higher parent, and FO x YK -23 where positive heterosis was observed. Inheritance of leaf number per stalk is intermediary and partially dominant. Dominance of the parent with higher leaf number was observed in O-87 x PV 156/1, negative heterosis was present in: O-87 x P 12-2/1, FO x P12-2/1 and FO x P-2 and positive heterosis in O-87 x P-2. The way of inheritance of leaf area is intermediary, partially dominant and dominant and no presence of heterotic effect was observed. The investigations can be used as a basis for further selection work.
