Abstract [Objective] This study aims to evaluate the nut traits of the dominant varieties of Ping􀆳ou hybrid hazelnuts cultivated in the northern Anhui and analyze the suitability of the varieties for processing, to provide a basis for the selection and popularization of the hazelnuts. [Methods] Nine varieties were selected as the dominant varieties based on their adaptation and yield in the northern Anhui. These varieties were analyzed and evaluated from different processing and utilization perspectives, such as baking, kernel, oil, and fresh-eating. [Results] (1) The distribution ranges of single nut mass, nut size, nut shape index, kernel mass, shell thickness, and kernel mass percentage of 9 dominant varieties were 2.54-4.40 g, 18.99 -21.49 mm, 0.67-1.02, 1.00-1.66 g, 1.53-2.41 mm, and 34.36%-47.01%, respectively. The distribution ranges of fat, protein, and soluble sugar contents were 50.50-58.00 g/(100 g), 21.10- 25.10 g/(100 g), and 4.08%-4.94%, respectively. (2) 8 fatty acids were detected from the hazelnut kernels, among which oleic acid was the highest with a distribution range of 81.21%-88.53%. The content of unsaturated fatty acids was 92.19%-94.61% among the total content of fat in hazelnut kernels. For mineral nutrition, the content of potassium, phosphorus, calcium, and magnesium in hazelnut kernels was relatively rich. (3) As for the processing capacity, the distribution ranges of single plant yield, fat production, and protein production of 9 dominant varieties were 1.52-2.20 kg, 330.50-503.47 g, and 141.68-224.40 g, respectively. [Conclusion] According to different consumption patterns, ‘Liaozhen 3’ is best for baking market, ‘Liaozhen 3’, ‘Dawei’ and ‘Liaozhen 4’ are best for kernel market, and ‘Dawei’, ‘Liaozhen 3’ and ‘Ping􀆳ou 545’ are best for the fresh-eating market. ‘Liaozhen 4’ can be used as oil processing varieties, ‘Liaozhen 1’ as functional protein beverage processing varieties, and ‘Dawei’ and ‘Liaozhen 9’ as high calcium processing varieties.
