Abstract :High temperature and its fluctuation influence bread wheat insert ignore into journalissuearticles values(Triticum aestivum L.); yield and quality before and after the grain filling stage in the Trakya region of Türkiye. Effect of the temperature between the Z24 and Z89 growth stages on yield, quality and some agronomic characters in bread wheat cultivars were investigated. This research was established with 25 genotypes in a randomised complete block design insert ignore into journalissuearticles values(RCBD); with 4 replications in Edirne and Tekirdağ locations, from 2010-2011 insert ignore into journalissuearticles values(E1); to 2015-2016 insert ignore into journalissuearticles values(E6); growing seasons. 5 common checks varieties were examined for their grain yield insert ignore into journalissuearticles values(GY);, 1000-kernel weight insert ignore into journalissuearticles values(TKW);, test weight insert ignore into journalissuearticles values(TW);, protein ratio insert ignore into journalissuearticles values(PRT);, wet gluten content insert ignore into journalissuearticles values(GLT);, gluten index insert ignore into journalissuearticles values(IND);, grain hardness insert ignore into journalissuearticles values(HARD);, sedimentation value insert ignore into journalissuearticles values(SED);, plant height insert ignore into journalissuearticles values(PH); and days of heading insert ignore into journalissuearticles values(DH);. There were various relationships among environment, cultivar and temperature. The mean grain yield was in the range of 4454-8158 kg/ha-1 across six environments, in the Edirne location and E4 was the highest yielding environment while E6 was the lowest. As a result of the environmental effect, there was a 83.2% difference between the highest and lowest yield. The highest TKW insert ignore into journalissuearticles values(47.2 g); was in E4 and the lowest insert ignore into journalissuearticles values(34.3 g); was in E1. Test weight varied across six environments the lowest was in E3 and the highest in E2. Environment E1 had a higher protein ratio and wet gluten content, and E4 had the lowest protein ratio and wet gluten content. The gluten index varied from the lowest in E6 insert ignore into journalissuearticles values(71.3%);, and the highest was 93.3 in E4. There was high variation in sedimentation value across six environments. The lowest value was in E4 insert ignore into journalissuearticles values(40.0 ml); and the highest was in 64.8 ml in E1. In the Tekirdağ location, the mean grain yield was in the range of 5485-8283 kg/ha-1, so there was a 51.0% difference between the highest and lowest yield. The highest insert ignore into journalissuearticles values(46.6 g); and lowest insert ignore into journalissuearticles values(39.5 g); TKW were in environments E2 and E1. Test weight varied across six environments the lowest was 81.1 kg in E4 and the highest was 85.2 kg in E2. Environment E3 had the lowest protein ratio, E1 had the lowest wet gluten content and E2 had the highest protein ratio and wet gluten content. Across six environments, the gluten index varied from the lowest in E2 insert ignore into journalissuearticles values(74.8%);, and the highest was 94.5 in E1. The lowest sedimentation was in E4 insert ignore into journalissuearticles values(42.2 ml); and the highest was in 47.0 ml in E5.
