Abstract :This study was carried out in the central land of Bahri Dağdaş International Agricultural Research Institute in 2017-2018 with 64 bread wheat varieties in rainfed and irrigated conditions according to the randomized blocks experimental design with 2 replications. In the trial, correlation coefficients of thousand kernel weight, protein content, test weight, Zeleny sedimentation, grain hardness, alveograph, farinograph and mixograph parameters were determined. Correlation analysis was carried out to determine the changes in the examined quality parameters in the study under different growing conditions. Correlation coefficients that were similar or different according to the conditions were determined in the examined quality parameters. In rainfed and irrigated conditions, positive correlations were determined between Zeleny sedimentation and mixograph peak height (0.447**,0.3569**), mixograph peak width (0.5054**,0.5725**) alveograph energy value (0.559**, 0.7278**) and farinograph development time (0.3661**, 0.4249**), respectively. Negative significant correlation was found between alveograph (G) and alveograph (P/L) ratio (-0.802**, -0.7765**). Positive correlation (0.5656**, 0.5484**) was found between farinograph water absorbtion and grain hardness (SKCS). Negative significant corelation was determined between mixograph peak area and farinograph softening degree in 12th minute (-0.528**, -0.5279**).
