1 Geçit Kuşağı Tarımsal Araştırma Enstitüsü, Eskişehir DOI : 10.21566/tarbitderg.281896 - The aim of the research conducted between 2010-2012 in Eskişehir is obtaining material and information for breeding of new varieties which can be used in rangeland improvement activities in Central Anatolia and alike regions. Some of the collected seeds were send with passport information to the Gene Banks in Ankara and İzmir. The rest of the seeds were grown in greenhouse and then transfered into field. In 2012, 38 populations were identified observing and measuring some characteristics. Then, mean and standart error values of the obtained data were determined. The mean values of the populations in main stem length, main stem thickness, flag leaf length, flag leaf width, internode length, number of nodes, growth pattern, winter resistance and tillering capacity were changed between 38.5-68.4 cm, 1.1-3.0 mm, 3.9-9.6 cm, 2.2-5.1 mm, 7.8-18 cm, 2.9-4.2, 6.2-8.8, 5.1-8.0, and 5.2-8.0, respectively. According to the correlation analysis to determine relationships between the characteristics, there were positively correlations between tillering capacity and main stem thickness (r=0.472**), tillering capacity and flag leaf length (r = 0.456**) and tillering capacity and flag leaf width (r = 0.453**). A negative correlation between winter resistance and flag leaf width (r = 0.379**) was also remarkable. Keywords : Crested wheatgrass, collection, breeding, gene bank, correlation
