چکیده

The first step in walnut breeding programs is to identify and evaluate superior genotypes of fruit trees. Hence, there are various walnut breeding programs in various areas of Iran. A study aimed to evaluate the morphological and chemical characteristics of selected superior genotypes of walnut was conducted in the Shahroud region in 2011-2012.  The following genotypes were selected in this study as the best walnut genotypes:  X-18 homogamous genotypes due to desirable late leafing;   genotype X-11 for its high percentage of kernel production, easily removal of shell, thin shell; genotype X-52 due to its kernel plumpness compared to other genotypes, thin shell and high percentage of kernel and genotype X-70 for its kernel brightness, easily kernel extracting and high percentage of kernels. The X-49 and X-5 genotypes had the highest amount of linoleic and linolenic fatty acids and higher nutritional quality compared to other genotypes. Three genotypes, X-3, X-11 and X-22, had the highest amount of oil. Genotypes X-9 and X-45 had the highest amount of protein. The difference between oil content and fatty acid compositions was presumably due to genetic diversity and ecological conditions of the studied genotypes cultivation.
