The study was conducted to obtain the genetic informations for some useful characters in tobacco breeding. The eight parents and a set of 28 crosses of F1's and F2's were used as materials, and planted on two different cultivated systems, i. e., oriental's and burley systems, during 1986-1988 at taegu Experiment Station, Korea Ginseng & Tobacco Research Institute. The observed characters were six agronomic characters which were plant height, number of leaves per plant, leaf length, leaf width, days to flowering, yield and five chemical components, nicotine, total nitrogen, protein nitrogen, total volatile base and pet, ether extract. The results obtaining are summarized as follows: 1. The higher heritabilities were found for days to flowering yield and nicotine in both generations, but values for number of leaves per plant, leaf length, total nitrogen and protein nitrogen were lower than other characters. 2. Genotypic correlation coefficients among all pairs of characters were slightly higher than the corresponding phenotypic correlations in F1's and F2's on two different cultivated systems. The relationship between leaf length and leaf width was the positive correlation, but that between number of leaves per plant and leaf width was negative. 3. From the genotypic correlations between yield and other characters, a conclusion that the yield was highly correlated with plant height, leaf length, leaf width and days to flowering was given. 4. Quality was positively correlated with number of leaves per plant and nicotine, but negatively with the other agronomic characters and chemical components.
