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 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 results of study, it is observed that Tuzluca region hosts valuable walnut genotypes and nutritious walnuts are found among these genotypes.
