Özet: Southeastern Anatolia Region is the gene center of durum wheat and the best quality wheat is grown in this region in terms of industrial sector. Landraces that have been adapting to the region for many years have gained importance in terms of natural products in recent times. These genotypes are also used in breeding programs and are important genetic resources. The quality parameters of some durum wheat varieties, lines and local populations were examined in this study conducted in Diyarbakır and Kızıltepe locations, with 2 replications according to randomized blocks trial design in the 2011-2012 growing season. In the study, 50 varieties, 25 landraces and 75 lines (total 150 genotypes) were used as materials. In the study, test weight, thousand kernel weight, protein content, vitrousness ratio, mSDS value and semolina color were investigated. While the varieties did not show any superiority for properties, the lines had superiority in terms of test weight, semolina color and mSDS values. Landraces were found to be lower in terms of test weight, semolina color and mSDS than varieties and lines, but higher in terms of protein content, vitreousness ratio and thousand kernel weight. As a result, it is understood that durum wheat landraces are important genetic resources in terms of quality and have significant potential for use in breeding programs.
