The study was carried out at Nuclear Institute for Food and Agriculture (NIFA), Peshawar, Pakistan during 2007-2008. Nut samples of 18 promising indigenous walnut genotypes along with two exotic varieties were collected and kernel were separated for determination of chemical composition. Our results indicate that percent fats ranged from 54.7-63.8, crude protein 10.5-14.5%, carbohydrates 13.1-26.9%, crude fiber 2.0-2.8%, ash 1.6-2.1% and moisture 1.3-4.9%. Genotypes Dr-62 and Dr-66 contained maximum (63.8%) fats while Ch-1 contained the highest protein content (14.5%). Carbohydrates and crude fiber were the highest (26.9 and 2.8%) in genotypes Sw-110 and Dr-61 respectively. Maximum percent ash (2.1%) was note for genotype Dr-62.
