[Genetic analysis of quantitative properties of tobacco]
1983
Naumovski, K.T.
Four varieties, namely P 10-3/2, Jk 7-4/2, Dzebel No 1 and Florija, have been used in the investigations of quantitative properties inheritance in tobacco. Genotype Dzebel 1 is the best and Florija the poorest combiner for the number of days between sprouting and flowering. Variety Dzebel 1 had the greatest number of dominant genes for this property. Additive and non-additive factors, with additive ones predominating, played an important role in stalk height, leaf number and middle belt leaf length inheritance. Variety P 10-3/2, being also the best combiner for the leaf number per plant, had the greatest number of dominant genes for height. Variety Jk 7-4/2 had the largest number of dominant genes for the leaf number. Genes having additive effects were important for the leaf width and the best combiner for this property was variety Florija. Additive and non-additive gene effects, with non-additive one predominating, were important for the yield of dry tobacco per plant. Variety Florija was the best combiner for this property. Genes with additive effects were important for the nicotine content and the best combiners were varieties Jk 7-4/2 and P 10-3/2, the latter having the largest number of dominant genes for this property.
