The purpose of this study was determine new tobacco cultivars with higher yields and better quality
properties for Tokat/Erbaa location in 2012-2013 years. Hybrids were produced from half-diallel crosses
between Xanthi-2A, Nail, Gümüşhacıköy, Taşova, Katerini, Canik and Erbaa tobacco varieties. The
experiment was designed according to the `Split Plots on Randomized Complete Block` with three
replications. Plant height, leaf width, leaf length, number of leaves, leaf yield, organoleptic observations,
nicotine and sugar rates were evaluated. General combining abilities of Nail cultivar for yield and Xanthi-2A,
Katerini and Taşova cultivars for quality were found to have positive effects. Specific combining abilities of
Xanthi-2A x Katerini, Nail x Katerini, Nail x Canik, Nail x Erbaa, Gümüşhacıköy x Canik, Katerini x Canik,
Katerini x Erbaa ve Canik x Erbaa hybrids for yield and Xanthi-2A x Taşova, Xanthi-2A x Katerini, Xanthi-2A
x Erbaa, Nail x Taşova, Nail x Katerini, Taşova x Katerini, Taşova x Erbaa ve Katerini x Erbaa hybrids for
quality were determined to have superior. Based on the results, Xanthi-2A x Katerini (170 kg/da yield, 75%
quality), Nail x Katerini (164 kg/da yield, 75% quality), Katerini x Erbaa (167 kg/da yield, 73% quality) and
Canik x Erbaa (184 kg/da yield, 68% quality) hybrids were found to have superior yield and quality traits than
Xanthi/2A cultivar that has produce in Erbaa location.
