Doğu Akdeniz Bölgesinde Yetiştirilen Yerfıstığı Genotiplerinde Verim Stabilitesi ve Genotip-Çevre İnteraksiyonu

Abstract

Amaç: Doğu Akdeniz bölgesinde yerfıstığı üretimi, farklı çevre koşulları nedeniyle olumsuz etkilenmektedir. Bu nedenle yüksek verimli ve stabil çeşitlerin belirlenmesi gerekmektedir. Bu çalışma, on yerfıstığı genotipinin verim performansını ve adaptasyon yeteneğini değerlendirmek ve çoklu ortamlarda genotip × çevre interaksiyonu belirlemek amacıyla yapılmıştır. Materyal ve Yöntem: Araştırma, iki yıl boyunca üç farklı lokasyonda (Adana, Osmaniye ve Kahramanmaraş) gerçekleştirilmiştir. On yerfıstığı genotipi, standart tarım uygulamaları altında test 2 Beycioğlu, T. & Kıllı, F. edilmiştir. Meyve verimi, genotip (G), çevre (E) ve genotip × çevre (G×E) interaksiyonunun etkilerini değerlendirmek için regresyon modelleri ve GGE Biplot metodolojisi kullanılarak analiz edilmiştir. Geniş ve spesifik olarak adapte olmuş çeşitleri belirlemek için mega-çevre yapıları ve stabilite parametreleri değerlendirilmiştir. Bulgular: Genotip, çevre ve G×E interaksiyonunun meyve verimi üzerindeki etkileri istatistiksel olarak önemli olduğu tespit edilmiştir. Sultan, farklı lokasyonlarda (bi < 1,0) özel adaptasyon göstererek en yüksek meyve verimini sergilerken, Halisbey tüm ortamlarda geniş bir adaptasyon sergilemiştir. Batem 5025 çeşidi ise belirli lokasyonlarda önde gelen çeşitlerden biri olarak tespit edilmiştir. GGE Biplot analizi sonucunda iki farklı mega-çevre oluştuğu ve genotiplerin farklı lokasyonlardaki stabilite ve verim performansları açıkça ortaya konulmuştur. Sonuç: Bu çalışma; verim performansı, çeşit seçimi ve bitki ıslah stratejilerinin geliştirilmesi açısından önemli bir bilimsel temel oluşturmaktadır. Sultan genotipi, spesifik adaptasyonu (bi < 1,0) nedeniyle stres koşullarına ve düşük girdili ortamlara özgü olarak önerilirken, Halisbey geniş adaptasyona sahip çeşit olarak önerilmektedir. Bulgular, çevreye uygun tarım stratejilerinin geliştirilmesine rehberlik ederek bölgesel yerfıstığı üretim verimliliğinin artırılmasına katkıda bulunmaktadır.

Yield Stability and Genotype by Environment Interaction in Peanut Cultivars Across the Eastern Mediterranean

Abstract

Objective: Peanut production in the Eastern Mediterranean region is constrained by variable environmental conditions, creating a need to identify high-yielding and stable cultivars. This study aimed to evaluate the yield performance and adaptation ability of ten peanut genotypes and to determine genotype × environment interactions across multiple environments. Materials and Methods: The experiment was conducted over two years at three locations (Adana, Osmaniye, and Kahramanmaraş). Ten peanut genotypes were tested under standard agronomic practices. Pod yield was analyzed using regression models and GGE Biplot methodology to assess the effects of genotype (G), environment (E), and genotype × environment (G×E) interactions. Mega-environment structures and stability parameters were evaluated to identify broadly and specifically adapted cultivars. Results: Genotype, environment, and G×E interaction effects on pod yield were statistically significant. Sultan exhibited the highest pod yield with specific adaptation to low-input and stress-prone environments (bi<1.0), while Halisbey demonstrated broad adaptation across all environments. Batem 5025 was identified as one of the leading genotypes in specific environments. GGE Biplot analysis identified two distinct mega-environments and clearly differentiated the stability and yield performance of genotypes across sites. Conclusion: The study demonstrates that combining yield performance with adaptation analysis provides a robust basis for cultivar selection and plant breeding strategies. Sultan is recommended for stress-prone and resource-limited environments due to its specific adaptation (bi<1.0), while Halisbey is recommended as a widely adapted cultivar. Region-specific genotypes should be considered to optimize productivity. The findings contribute to improving regional peanut production efficiency by guiding the development of environment-tailored agricultural strategies.
