Abstract:

 This study was conducted in four different environments representing the Thrace region during the 2020-2021 season to evaluate genotype x environment interaction GEI using the principal component PC, genotype x environment biplot GGE biplot and AMMI analyses for a total of 27 varieties and candidate varieties for grain yield and some important quality traits. The experiments were carried out in a randomized complete block design with four replications. Agricultural and quality traits including heading date, plant height, grain yield, thousand grain weight, volume weight, grain hardness, protein ratio, Zeleny sedimentation, Alveograph energy value, wet gluten content, and gluten index were examined in this study. The highest variation in grain yield was determined in Tekirdağ, while the highest yield was in Edirne in average. GGE biplot analysis revealed that two different mega-environments were determined, and two main components explained a total of 89.97 of the GEI. The AMMI-based variance analysis also revealed statistically significant effects for genotype, environment, replication, and GEI. The most stable genotypes were determined as Ez11 and Rumeli, with the LG Arnova variety being one of the four genotypes prominent in all four environments. Correlation analysis resulted in statistically significant positive relationships p0.05 between quality traits, whereas no significant relationships were observed between grain yield and other agricultural and quality traits. The first four PCs had eigenvalues exceeding 1, explaining more than 74 of the total variation. LG Arnova, Artek, Axum, Alpan, and Vassa varietiescandidate varieties have particularly stood out for grain yield in all environments. To obtain more concrete data in this regard, further studies need to be conducted for a longer period in these environments.

 Bu çalışma, toplamda 27 çeşit ve çeşit adaylarının dane verimi ve bazı önemli kalite özellikleri bakımından genotip x çevre etkileşimi temel bileşen, GGE biplot ve AMMI analizleri değerlendirmek amacıyla Trakya bölgesini temsil eden dört farklı çevrede 2020-2021 sezonunda yürütülmüştür. Denemeler tesadüf blokları deneme desenine göre dört tekerrürlü yürütülmüş olup ve tarımsal ve kalite özelliklerinden başaklanma gün sayısı, bitki boyu, dane verimi, bin dane ağırlığı, hektolitre ağırlığı, dane sertliği, protein oranı, Zeleny sedimantasyon, Alveograf enerji değeri, yaş gluten oranı ve gluten indeksi çalışma kapsamında incelenmiştir. Çalışmada, dane veriminde en yüksek varyasyon Tekirdağ çevresinde belirlenmiş olup en yüksek verim ise Edirne çevresinde belirlenmiştir. GGE biplot analizine göre iki farklı mega çevre oluşmuş ve iki temel bileşen toplamda 89.97 genotip x çevre ilişkisini açıklamıştır. AMMI temelli varyans analizi sonucunda ise genotip, çevre, tekerrrür ve genotip x çevre interaksiyonu bakımından istatistiki olarak önemli etkiler tespit edilmiştir. En stabil genotipler ise Ez11 ve Rumeli olarak belirlenirken LG Arnova çeşidi dört çevrede de öne çıkan dört genotipten biri olmuştur. Korelasyon analizine sonucunda kalite özellikleri arasında istatistiki olarak önemli p0.05 pozitif ilişkiler tespit edilirken dane verimi ile diğer tarımsal ve kalite özellikleri arasında anlamlı bir ilişki belirlenmemiştir. İlk dört temel bileşen 1in üzerinde eigen değerine sahip olarak bulunmuş ve varyasyonun 74ünden fazlasını açıklamıştır. LG Arnova, Artek, Axum, Alpan ve Vassa çeşitçeşit adayları özellikle dane verimi bakımından ilgili çevrelerde öne çıkan çeşitler olmuşlardır. Bu konuda daha detaylı sonuçlar elde etmek için genotiplerin ilgili çevrelerde daha uzun süreyle denenmesi gerekmektedir.
