Abstract

An experiment was carried out to assess flag leaf fresh and dry weight of advanced bread wheat genotypes and their relation with yield and yield components. A total of 25 bread wheat genotypes were tested during the 2017-2018 cycles in four locations in the Trakia region, Turkey. The experiment was conducted in a randomized complete blocks design (RCBD) with four replications. Grain yield (GY), spike number per square meter (SNM), kernel number per spike (KNS), spikelet number per spike (SNS), spike weight (SW), plant height (PH), peduncle length (PL), spike length (SL), flag leaf fresh weight (FLFW), flash leaf dry weight (FLDW) were investigated. The combined ANOVA revealed significant differences among genotypes (G), environments (E) and their interaction (G×E) for grain yield (p<0.01). The highest grain yield was performed by G21 (6807 kg ha-1) and G20 (6776 kg ha-1). Both genotypes also had higher yield potential across four environments. Therefore, they were considered stable genotypes. Flag leaf fresh and dry weight in wheat genotypes positively affected spike length, spikelet number per spike, kernel number per spike and spike weight. As the plant density per unit area increased, there was a decrease in flag leaf fresh and dry weight. Increasing in the spike number per square meter negatively affected and reduced flag leaf fresh and dry weight in wheat genotypes. Results showed that spike weight, flag leaf fresh and dry weight of the wheat genotypes could be used in the selection of wheat breeding study for yield components. The longest spike, the highest number of grains per spike and the number of spikelets were determined in G17, together with the yield above the average. In addition, G17 had the highest spike weight and flag leaf fresh and dry weight. For this reason, G17 has been determined that can be used in breeding studies due to its agronomic characteristics. The results of the research showed that flag leaf dry and fresh weight could be used for yield components in wheat breeding selection under rainfed conditions.
