Experiment was set up in 2008-2009 growing season in Edirne and Tekirdağ locations with 25 genotypes in randomized completely blocks design with four replications. Grain yield, plant height, lodging resistance, date of heading and maturity, resistance to powdery mildew and net blotch, 1000 kernel weights, test weight and protein ratio and relationship among these characters were investigated. The results showed that there were significant difference among the genotypes than grain yield and some other investigated characters. Mean grain yield of the genotypes was 524.1 kg/da, and the highest grain yield with 619.5 kg/da was determined in Martı cultivar. Mean yield was 488.3 kg/da and 560.0 kg/da in Edirne and Tekirdağ locations respectively. Plant height ranged between 89.5 cm and 108.5 cm. In Trakya region mainly widely disease is net blotch (Drechslera teres f. teres) and it was determined that almost all genotypes were medium susceptible to net blotch. The highest 1000 kernel wight was determined in TEA1619-20 and test weight in TEA1619-17 lines. According to protein ratio there was significant differences among genotypes and highest protein was determined with 12.5% in Lord cultivar. The highest grain yield was determined in genotypes with early maturating and tall plant height. Identifying positive relationship between lodging resistance and plant height (r=0.871**) it was showed that this character can be used for lodging resistance. Martı, Hasat, TEA1619-17 and TEA1619-20 had most prominent genotypes based on yield and some other investigated characters. Keywords : Barley, genotype, yield, agronomic characters
