摘要：In this study some physical and chemical properties of walnut genotypes grown in 5 different regionsaround Van Lake (Eastern Anatolia) harvested during ripening period have been determined. Theaverage kernel ratios of ripe fruits from Adilcevaz, Ahlat, Edremit, Çatak and Hakkari found to be45.7, 45.0, 42.2, 43.1 and 38.4%, respectively. The oil contents of fruits considerably increased duringripening and ranged between 65.7 and 70.7% in ripe walnuts. Linoleic acid was the most abundant fattyacid in walnut followed by oleic acid. The unsaturated fatty acids contents of samples remarkablyincreased during ripening. The tocopherol contents of walnuts considerably increased during ripening.The initial and final total tocopherol contents of samples varied between 8.3-18.5 and 121.9-135.4mg/100 g oil, respectively. Potassium was the most abundant mineral in ripe walnuts followed by Mgand Ca. The results showed that these genotypes were promising walnut types and selection researchesshould be carrying out to produce standard walnut types from this genotypes.
