Turkey is an important tobacco producing country and leading the world in oriental tobacco production. In the present study, effect of heterosis on yield and quality of oriental tobacco was investigated, and development of oriental tobacco hybrids with high yield and quality properties for Black Sea region of Turkey was targeted. Seven oriental tobacco genotypes with considerable acreages in Turkey (Xanthi-2A, Nail, Gümüşhacıköy, Taşova, Katerini, Canik, Erbaa) and 21 hybrids produced by halfdiallel crosses among them were compared. Field trials were conducted in Erbaa and Bafra locations in 2012 and 2013 growing periods. Cured leaf yields, reducing sugar and nicotine contents of leaves and expertise quality were studied. Xanthi-2A × Katerini (1.70 t ha -1 cured leaf yield and 75% quality grade index) and Nail × Katerini (1.64 t ha -1 cured leaf yield and 75% quality grade index) hybrids showed good yield and quality properties in Erbaa conditions, while Nail × Katerini (1.88 t ha -1 cured leaf yield and 75% quality grade index) and Katerini × Erbaa (1.65 t ha -1 cured leaf yield and 78% quality grade index) had good yield and quality properties in Bafra conditions. It has been concluded that hybrid cultivars that can meet the demands of tobacco sector could be developed from some currently grown oriental tobacco cultivars in Turkey. Based on average of locations, an average of 16.20% and 6.85% heterosis were found as the average of all hybrids for cured leaf yield and expertise quality. Yield effects due to heterosis could be increased in future by adopting growing techniques adjusted for hybrids.

This study was conducted to evaluate the effect of autumn and spring sowing and row spacings (20, 30, 40, 50 and 60 cm) on yield, yield components and crude oil percentage of mustard (Sinapis arvensis L.) at eight locations lying in different ecological zones (Ankara,

Mustard is grown in mild winter regions as late fall and in hard winter regions as late spring crop. Mustard has high degree of adaptability under wide range of climatic conditions in Turkey. Temperature is an important weather parameter affecting the growth and development of the mustard. The sum growing degree day (GDD) for a growing season is related to plant development which is depends on the accumulation of heat. The aim of this study was to determine the adaptation of mustard, under sowing seasons (spring and fall sowing) and locations in terms of crop growth (emergence, 50% flowering, physiological maturity, and sum growing degree days) and seed yield of mustard. Two-year field experiments in a split-plot design with four replications were carried out during 2013-14 and 2014-15 growing seasons at eight different ecological locations. These locations included Ankara,

Tobacco (Nicotiana tabacum L.) is a plant grown for leaves. Leaves are dried and fermented to use in tobacco products. Oriental tobacco is widely consumed in the world due to its good aroma qualities. For this, different chemical and quality properties of Oriental tobacco lines, which have undergone small changes over time, have been examined. The samples (27 lines and 1 variety (Xanthi 2A)) obtained from tobacco lines grown in three different locations (Bagpinar, Evciler and Yenice) in Tokat and Canakkale were used in this study. Quality index, nicotine, glucose, fructose, chlorogenic acid and rutin amounts were determined to investigate the effect of geographical environment on tobacco lines. Chemical analyzes were performed using high performance liquid chromatography. The data obtained from the chromatographic analyzes and quality index were evaluated by using principal component analysis. These three different locations were generally separated and clustered. Due to its geographical locations, genotypes better adapted in the Bagpinar location.

The present study was conducted to determine the performance of summer and winter-sown camelina lines in 2013-2014 and 2014-2015 growing seasons. In experiments, 11 camelina genotypes (

The study was conducted to determine the impacts of environmental variations on yield and yield related properties of tobacco. The experimental layout was in the randomized blocks with three replicates in four different locations (Erbaa-Evciler, Erbaa-Karayaka, Gümüşhacıköy, Bafra) using 21 lines and four standard varieties that stand out with their different characteristics. The variation in plant height, number of leaves, leaf width, leaf length and leaf yield of genotypes were investigated at different ecologies. All the parameters investigated of the genotypes have been significantly affected by changing environmental conditions. Plant height ranged from 49.33 cm to 177.32 cm, the number of leaves from 21.83 to 47.10 per plant, leaf width from 6.83 to 16.31 cm, leaf length from 13.01 to 28.93 cm, and yield ranged from 79.17 kg-1 to 238.98 kg da-1. The results for the performances of genotypes in all environments showed that
