Abstract

Four oriental tobacco cultivars (P 10-3/2, P-26, PV156/1, Smirna) and six of their diallel F1 hybrids were investigated in 1998, 1999 and 2000, to study the environmental and genetic variability for the characters stalk height and number of leaves per stalk. The experiment was set up in the field of Tobacco Institute-Prilep in a randomized block design with four replications. Measurements were made in the period of maximum expression of tobacco and the data obtained were processed by the analysis of variance after Svab (1973). There were significant differences among cultivars in relation to the characters investigated. The low variability obtained is an indicator of high genetic homogeneity. The genotype analysis revealed a higher effect of additive component in the inheritance of these two characters. The components of genetic variability in the material investigated during three years differed. It might be stated that genetic control on investigated characters varies in a different way, depending on the environmental conditions. Thus, for the character stalk height, environmental variability is greater than for the character number of leaves per stalk. This method of work, applied in a greater number of characters, will find implementation in selection for quantity and quality improvement and for adequate regional distribution of tobacco varieties.
