Walnut (Juglans regia L.) is a plant that has significant economical value and medicinal importance for human health. It is consumed in large quantities by people, therefore, it has a very important place in the public nutritive habits. Turkey has a very good walnut population of walnut varieties when compared to other parts of the world. Our objective was to investigate kernel properties and fatty acid composition, proximate composition and minerals of genotypes that are commonly grown in Turkey. Investigated genotypes were Sebin-Type-I, Körcegöz, Karabodur, Tozam and Güvenli. Physical properties are attributed to quality criteria of nuts. Sebin Type-I and Güvenli showed a good quality according to the test results. Average fatty acid compositions of genotypes (%) were 16:0; 6.88, 18:0; 7.50, 18:1; 21.16, 18.2; 43.41, 18:3; 6.25: 20:0; 11.75 for Sebin-Type-I, Körcegöz, Karabodur, Tozani and Güvenli, respectively. Proximate compounds (%) were: protein, 13.77; ash, 1.81; moisture, 2.98; fat, 62.84; total carbohydrate, 18.67. Average mineral contents (mg/100 g) were: P, 316.0; K, 270.0; Ca, 85.0; Mg, 90.0; Zn, 2.01; Mn, 2.46; Cu, 1.01; Fe, 2.90; B, 1.03.
核桃（胡桃）是一种对人类健康具有重要经济价值和药用价值的植物。人们大量食用核桃，因此，它在公众营养习惯中占有非常重要的地位。与世界其他地区相比，土耳其拥有非常优良的核桃品种群体。我们的目标是研究土耳其常见种植基因型的果仁特性、脂肪酸组成、近似成分和矿物质。所研究的基因型为塞宾一号型、科尔切戈兹、卡拉博杜尔、托赞和居文利。物理特性归因于坚果的质量标准。根据测试结果，塞宾一号型和居文利表现出良好的品质。各基因型的平均脂肪酸组成（%）分别为：塞宾一号型、科尔切戈兹、卡拉博杜尔、托扎尼和居文利的16:0为6.88、18:0为7.50、18:1为21.16、18:2为43.41、18:3为6.25、20:0为11.75。近似成分（%）为：蛋白质13.77、灰分1.81、水分2.98、脂肪62.84、总碳水化合物18.67。平均矿物质含量（mg/100 g）为：磷316.0、钾270.0、钙85.0、镁90.0、锌2.01、锰2.46、铜1.01、铁2.90、硼1.03。
