Abstract (2. Language): 
Walnuts (Juglans regia L.) of 14 new genotypes were selected according to late leafing time, fruit quality and high yield in native population in Niksar-Turkey. Crude protein, total oil and ash contents of walnut kernels ranged from 17.09-23.89 %, 62.80-73.05 %, and 1.36 %-2.20 % respectively. Phosphorous contents of kernels were found in the range of 230.65-344.40 mg 100 g-1, potassium 163.92-308.86 mg 100 g-1, sodium 7.94-22.53 mg 100 g-1, copper 2.25-3.64 mg 100 g-1, iron 2.21-4.32 mg 100 g-1, zinc 1.97-5.48 mg 100 g-1, manganese 0.91-4.39 mg 100 g-1. Differences in chemical properties and fatty acid contents were determined. Polyunsaturated especially linoleic acid was found predominant. Oleic, linolenic, palmitic and stearic acids were other main fatty acids in oil of walnut kernels. Also, 13 different fatty acids were determined by at small quantities. Total PUFA content changed between 58.77 % and 77.39 %.

Abstract (Original Language): 
Geç yapraklanma, meyve kalitesi ve yüksek verim esas alınarak Niksar ceviz popülasyonundan 14 genotip seçilmiştir. İç cevizde ham protein, total yağ ve kül içeriği sırasıyla 17.09-23.89 %, 62.80-73.05 %, 1.36-2.20 % arasında belirlenmiştir. Fosfor içeriği 230.65-344.40 mg 100 g-1 arasında, potasyum içeriği 163.92-308.86 mg arasında, sodyum içeriği 7.94-22.53 mg arasında, bakır içeriği 2.25-3.64 arasında, demir içeriği 2.21-4.32 arasında, çinko içeriği 1.97-5.48 arasında, manganez içeriği 0.91-4.39 arasında tespit edilmiştir. Genotiplerin kimyasal içerikleri ve yağ asitleri kompozisyonları arasında farklılıklar belirlenmiştir. Çoklu doymamış yağ asitleri içinde linoleik asit dominant bulunmuştur. İç ceviz yağında, ana yağ asitleri oleik, linolenik, palmitik ve stearik asitlerdir. Ayrıca eser miktarlarda 13 farklı yağ asidi de tespit edilmiştir. Total ÇDYA içeriği % 58.77 ile % 77.39 arasında belirlenmiştir.
