Résumé
This study was carried out for 2 years in the Akyurt (altitude 960 m) district of Ankara province during the 2018/2019 and 2019/2020 production seasons. The experiment was set up in a randomized block design with 3 replications in wet and dry conditions. Genotypes ; Selimiye, Kransuia Odeska, Bayraktar, Rumeli, Havva Bacı, Alka, Altay 2000, Renata, Dropia, Duru 17, Sönmez, Flamura 85, Kralijca, Nomade, Albachiara, Pehlivan, Gelibolu, Syriena, Odeska, Miranda and Beoma 1 were tested for yield components. Using Path and Principal Main Component Analysis, genotypes having higher performance, quality, and stability, and effective components on seed yield were determined. In our study, Selimiye, Bayraktar, Syriena Odeska, and Altay genotypes were determined as higher performance and quality in all components examined, including grain yield under irrigated and arid conditions. The performances of the cultivars in irrigated conditions were significantly higher than in arid conditions. Principle component and biplot analyses revealed that seed number per spike, days to flowering, plant height, spike number per m², the grain weight per spike, SPAD, chlorophyll a, and chlorophyll b are closely related to seed yield. In terms of genotypes, Rumeli, Hava Bacı, Krasunia Odeska, and Altay 2000 could be recommended for seed production. Using genotypes, high-yielding, high quality, resistant to stress conditions (biotic and abiotic stresses), and stable for these characteristics in wheat production will play an important role in increasing the yield.
