TAILIEUCHUNG - Stability of grain vitreousness in durum wheat (Triticum durum L. Desf.) genotypes in the North-Western region of Turkey

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. | Turk J Agric For 31 (2007) 313-318 © TÜB‹TAK Stability of Grain Vitreousness in Durum Wheat (Triticum durum L.

Grain vitreousness percentage of the genotypes ranged between and . 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 K›z›ltan 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.
