Determination of Biochemical Properties and Fatty Acid Composition of New Walnut (Juglans regia) Genotypes

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 %.
