Abstract: The experiment was carried out to asses of yield and yield components of advanced durum wheat genotypes under rainfed conditions. A total of 15 durum wheat genotypes were examined during the 2016-2017 and 2017-2018 growing cycles in the Edirne location in the Trakia region, Turkey. The experiment was conducted in a randomized complete blocks design (RCBD) with four replications. In the experiments, grain yield, days of heading, plant height, peduncle length, spike length, kernel number per spike, spikelet number per spike and flag leaf area were investigated. The results of variance analysis revealed significant differences (p<0.01) among genotypes and year × genotypes interaction for yield and yield component. The mean grain yield was 6675 kg ha-1 in 2016-2017 and 5905 kg ha-1 in the 2017-2018 cycles. The highest grain yield was performed by G9 (6826 kg ha-1) and the lowest by G14 (6798 kg ha-1). In the experiment, G4 had the longest peduncle length (34.65 cm) and G11 had the longest spike length (9.43 cm). The highest spikelet number per spike and kernel number per spike was found in G3 Genotype G15 had the highest flag leaf area (59.57 cm2). In the study, flag leaf area in durum wheat genotypes significantly affected kernel number in spike. Tall and late maturing genotypes had higher spike length and spikelet number per spike. Grain yield was negatively correlated with spike length, days of heading and plant height. The fact that there was a different correlation between the parameters revealed the importance of genotype and environmental effects. In the study, it was found to be significant genotypes and year genotype interaction among the parameter peduncle length, spike length, kernel number per spike, spikelet number per spike and flag leaf area. Therefore, it was concluded that these parameters can be used in selection in breeding studies.
