Influence of variety and location on fatty acid composition and protein content of peanuts (Arachis hypogaea L.) in two locations of Türkiye

Abstract

Objective: This study aimed to evaluate the fatty acid compositions, oil quality factors (such as oleic/linoleic acid ratio and iodine value), and protein content of four peanut varieties (Masal, NC-7, Halisbey, and Rigel) grown during the main season in two different locations (Şırnak and Osmaniye). Material and Methods: Field experiments were conducted using a randomized complete block design with three replications at each location. It was determined that the oil and protein contents of peanut seeds, as well as oil quality parameters, including fatty acid composition, the oleic/linoleic acid ratio, and iodine value. Results: The effect of variety was significant (p<0.05) for all quality parameters measured, except for oil content. The composition of oleic, palmitic, and stearic acids was significantly influenced by location (p<0.05). The Halisbey variety exhibited the highest protein content (22.17%). Conclusion: The study revealed a significant genotype × environment interaction, highlighting that location is a decisive factor in varietal performance. The Masal variety was identified as the most stable and superior genotype across both locations, characterized by its high oleic acid content (approx. 50% higher than others), a superior O/L ratio, and the lowest iodine value. It was concluded that the Masal variety is a promising candidate for cultivation in both Şırnak and Osmaniye conditions to achieve premium oil quality and extended shelf life.

Amaç: Bu çalışma, iki farklı lokasyonda (Şırnak ve Osmaniye) ana ürün koşullarında yetiştiriciliği yapılan dört farklı yerfıstığı çeşidinin (Masal, NC-7, Halisbey ve Rigel) yağ asitleri kompozisyonu, yağ kalite faktörleri (oleik/linoleik asit oranı ve iyot değeri gibi) ve protein oranını belirlemeyi amaçlamıştır. Materyal ve Yöntem: Araştırma, her iki lokasyonda tesadüf blokları deneme desenine göre üç yinelemeli olarak yürütülmüştür. Yağ ve protein içerikleri ile yağ kalite parametreleri arasında yağ asidi kompozisyonu, oleik/linoleik asit oranı ve iyot değeri incelenmiştir. Araştırma Bulguları: Çeşidin yağ içeriği dışındaki tüm özelliklerde (p<0,05) önemli etkisi bulunmuştur. Oleik asit, palmitik asit ve stearik asit ise lokasyondan önemli (p<0,05) seviyede etkilenmiştir. En yüksek protein içeriği Halisbey çeşidinde (%22,17) gözlenmiştir. Sonuç: Çalışma, önemli bir genotip x çevre etkileşimi ortaya koymuş olup, lokasyonun çeşit performansında belirleyici bir faktör olduğunu vurgulamaktadır. Masal çeşidi, her iki lokasyonda da en stabil ve üstün genotip olarak belirlenmiştir. Yaklaşık %50 daha yüksek oleik asit içeriği, üstün O/L oranı ve en düşük iyot değeri ile karakterize edilmiştir. Masal çeşidinin, üstün yağ kalitesi ve uzun raf ömrüne ulaşmak için hem Şırnak hem de Osmaniye koşullarında yetiştiricilik için umut verici bir aday olduğu sonucuna varılmıştır.
