											        				In this study, 36 bread wheat genotypes were tested to determine grain yield and some quality traits (protein content, protein yield, dry gluten content, mini-SDS sedimentation value and thousand kernel weight) in locations of Konya, İçeri Çumra and Obruk, during 2005-2006 growing season. Grain yield ranged from 154.58 kg/da to 258.43 kg/da, thousand kernel weight from 24.13 g to 36.60 g, dry gluten content from 9.58 % to 13.90 %, mini-SDS sedimentation value from 9.50 ml to 13.75 ml, protein content from 11.88 % to 15.43 % and protein yield from 20.07 kg/da to 33.17 kg/da. Genotypes were significantly different (P≤0.01)for the traits studied. Grain yield was positively correlated with thousand kernel weight and protein yield, while protein content with dry gluten content and mini-SDS sedimentation value. On the other hand, protein content was negatively correlated with thousand kernel weight and grain yield, while mini-SDS sedimentation value with grain yield. Correlations among yield and quality traits changed under different locations.
