Abstract
Yield and quality attributes of 13 bread wheat cultivars registered for
Thrace region in 2018 and 5 standard bread wheat cultivars were determined
and compared in this study. Tested cultivars are originated from Turkey,
Bulgaria, Romania, Croatia, Austria and Ukraine. Experiments were conducted
in 2015-2016 and 2016-2017 growing seasons. Since the locations were not
equally distributed to growing seasons, statistical analyses for yield and
other parameters were performed through assuming each location as an
environment. Therefore, assessments were made over 7 environments.
Environment (E) explained 54.9% of the total variation (E+G+GEI), genotype
(G) and genotype ? environment interaction (GEI) generated 25.6% and 19.5%,
respectively. GGE (Genotype + Genotype by environment interaction) biplot
analysis was able to explain 78.51% of variation in grain yield. Trial
environments gathered under 3 mega-environments. Of the cultivars registered
in 2018, Adali, Bc Anica, Topkapi, FDL Miranda, Otilia, ZT Ziyade, Viktoria
and Dragana had values larger than the average and thus they had the largest
PC1 (Principal component 1) scores. Tested cultivars were also assessed
based on vector lengths to average environment coordinate (AEC). Adali
cultivar with a high PC1 score and the closest position to AEC apsis was
found to be quite prominent for grain yield. In environment-focused
assessments, E3, E4 and E5 had the closest position to ideal environment
circle. With regard to physical quality attributes, Pehlivan, Bojana and
Adali cultivars had high performance values. The cultivar Bojana, Topkapi
and Iveta had protein contents above 15%. For Zeleny sedimentation values,
Krasunia odes?ka had the best performance.
