Summary
Bu araştırma, Iğdır’ın Tuzluca ilçesi merkez ve köylerinde yürütülen seleksiyon çalışması neticesinde ümitvar olarak seçilen 34 ceviz genotipi üzerinde yürütülmüştür. Çalışmada seçilen genotiplerin bazı fiziksel, kimyasal özellikleri ve mineral madde içeriklerinin belirlenmesi amacıyla bazı ölçüm ve analizler yapılmıştır. Seçilen genotiplerde meyve ağırlığı, iç ağırlığı, iç oranı ve kabuk kalınlığı sırasıyla 8.14-13.94 g, 4.01-6.49 g, % 34.84-53.91, 1.23-2.46 mm arasında değişmiştir. Genotiplerde yağ oranı % 50.52-66.68, protein oranı % 6.59-26.57, kül oranı % 0.98-4.00 ve nem oranı % 2.55-6.98 arasında kaydedilmiştir. Ceviz örneklerinde makro elementlerden N, P, K, Ca, Mg, Na ve mikro elementlerden ise Fe, Cu, Zn ve Mn içerikleri belirlenmiştir. Genotiplerde ortalama olarak % 1.83 N, 335.76 mg 100g-1 P, 493.49 mg 100g-1 K, 260.79 mg 100g-1 Ca, 234.40 mg 100g-1 Mg, 12.71 mg 100g-1 Na, 12.47 mg 100g-1 Fe, 2.88 mg 100g-1 Cu, 2.58 mg 100g-1 Zn ve 3.35 mg 100g-1 Mn bulunmuştur. Çalışma verilerine göre Tuzluca bölgesinin değerli ceviz genotipleri barındırdığı ve bu genotipler içerisinde besin değeri yüksek cevizler bulunduğu görülmüştür.

Abstract
This study was conducted on 34 walnut genotypes selected as promising as a result of selection study carried out in centre and villages of Tuzluca district, Iğdır. Some measurement and analysis were performed in order to determine some physical and chemical properties and mineral matter contents of genotypes selected in the study. Nut weight, kernel weight, kernel ratio, and shell thickness of selected genotypes varied in a range of 8.14-13.94 g, 4.01-6.49 g, 34.84-53.91%, and 1.23-2.46 mm, respectively. For the genotypes, following values were recorded; oil rate as 50.52-66.68%, protein rate 6.59-26.57%, ash rate 0.98-4.00%, and moisture rate 2.55-6.98%. Contents of N, P, K, Ca, Mg, and Na from macro elements and Fe, Cu, Zn, and Mn from micro elements were determined in walnut samples. Averagely 1.83% N, 335.76 mg 100g-1 P, 493.49 mg 100g-1 K, 260.79 mg 100g-1 Ca, 234.40 mg 100g-1 Mg, 12.71 mg 100g-1 Na, 12.47 mg 100g-1 Fe, 2.88 mg 100g-1 Cu, 2.58 mg 100g-1 Zn, and 3.35 mg 100g-1 Mn were found in genotypes. According to data of study, it is observed that Tuzluca region hosts valuable walnut genotypes and nutritious walnuts are found among these genotypes.
