This study was carried out in order to determine the grain vitreousness percentage and stability performance of 44 durum wheat genotypes, which were tested in 3 different environments during 2 growing periods. Grain vitreousness percentage of the genotypes ranged between 69.2% and 90.0%. Svevo, Amanos 97, and Zenit varieties had the highest vitreousness kernel percentages and the lowest grain yields. The negative correlation coefficient between vitreous grain percentage and grain yield, according to correlation analysis, confirms this result. Mutant 47, Harran 95, Epidur, and Kızıltan 95 were the most stable genotypes with respect to all stability parameters studied for vitreousness. Therefore, they can be recommended for profitable grain yield and consistent quality durum wheat production in the north-western region of Turkey. Svevo, Amanos 97, Zenit, Gediz 75, Ankara 98, Mirzabey, and Fuatbey 2000 varieties could be used as progenitors in future breeding programmes due to their high grain vitreousness potentials.
