The aim of this study was to determine the GY (grain yield) and some quality characters of durum wheat landraces under Thrace Region ecological conditions. This study was carried out in randomized complete blocks design with three replications in the locations of Tekirdağ, Edirne, Kırklareli and Lüleburgaz during the growing years of 2009 and 2010. In the research, 20 durum wheat landraces obtained from different regions of Turkey and 5 obsolete durum wheat cultivars were used as the

... l material. It was determined that the GY, TW (test weight) and PC (protein content) in the first year were higher than the second year in this study. The highest values for GY, TGW (thousand grain weight), and TW and GVR (grain vitreousness rate) were determined in Tekirdağ location, while the highest PC was determined in Edirne location. The results of the research showed that GY varied between 321.17-470.33 kg da -1 in Tekirdağ, 301.33-404.00 kg da -1 in Edirne; 197.50-334.67 kg da -1 in Kırklareli and 280.00-501.33 kg da -1 in Lüleburgaz. TGWs were determined between 38.17-44.50 g of Tekirdağ, 36.00-43.00 g of Edirne, 38.43-43.67 g of Kırklareli and 35.33-45.67 g of Lüleburgaz. TW of Tekirdağ, Edirne, Kırklareli and Lüleburgaz locations changed between 74.67-79.33 kg hl -1 , 69.33-76.83 kg hl -1 , 70.00-75.17 kg hl -1 and 71.00-77.50 kg hl -1 , respectively. The GVR was determined among 85. in Lüleburgaz. The PC of grains was measured among 13. in Kırklareli, and 13.40-16.53% in Lüleburgaz. It was determined that Dicle and Dicle-13 landraces for GY and TW, Adıyaman landrace for TGW, Çanakkale and Akbuğday landraces for the GVR, and İskenderun, Akbuğday, Erzincan landraces for PC have the highest values.
