| Summary: | Gümüşhacıköy Basma is famous for its aromatic structure in oriental type tobacco. However, it is known that new types of oriental tobacco have become widespread by adding Taşova, Erbaa and Niksar lines to the production area of this type of tobacco, especially due to the decrease in production since the beginning of 2000s. In this study, yield and quality performances of some oriental tobacco parents and hybrids in Gümüşhacıköy ecological conditions and heterosis and heterobeltiosis values of these hybrids were emphasized. Hybrid lines were obtained in 2016 by half-diallel hybridization from Xanthi-2A, Erbaa, Nail, Katerini and Canik 10821 (Sıtmasuyu) genotypes. The study was carried out with 5 parents and 4 F1 populations with their hybrids. Yield and yield related characteristics (plant height, number of leaves, leaf width and height), as well as glucose, fructose, nicotine, chlorogenic acid and routine contents were examined. It was determined that genotypes showed significant differences in all traits except leaf length. Hybrids outperformed their parents in all parameters except plant height and number of leaves. This advantage was 8.42% in yield, 7.73% in quality, 8.64% in reducing sugar, 3.49% in nicotine and 15.20% in chlorogenic acid + routine. The effect of leaf width on yield and chlorogenic acid + routine content on quality were determined. As a result of the study, when heterosis and heterobeltiosis data were evaluated, it was found that Xanthi 2A x Katerini hybrid showed promising results.
