Abstract The research was carried out in the 2018-2019 wheat growing season in order to determine the morphological characteristics and yield parameters of some bread wheat genotypes in Diyarbakır conditions. In the research, 8 advanced bread wheat lines (Triticum aestivum L.) and 12 cultivars were used as material. The experiment was set up in a randomized block design with three replications. In the study, anthesis time (days), plant height (cm), spike length (cm), spikelet numbers (pieces), grain numbers (pieces), grain weight (g), thousand grain weight (g) and grain yield (kg/da). ) parameters were examinated. Significant differences were found between genotypes in terms of the parameters examined in the study. According to the results; anthesis time :101.0-104.67 days, plant height: 60.20-87.67 cm, spike length: 6.90-9.43 cm, spikelet numbers: 15.33-17.87, grain numbers: 25.47-42.0, grain weight: 0.79-1.38 g, thousand grain weight: 23.59- 37.12 g and grain yield: 102.66-251.92 kg/da. As a result; it was determined that 11 STEM 6106 and 18 FHBSN 6439 lines gave high values ​​in terms of grain yield and these genotypes were promising genotypes that could be grown in Diyarbakır dry conditions.
