Abstract
To address the existing issue of ambiguous walnut varieties for oil processing, this study employed 26 main planted walnut varieties as the research object, completely analyzing their oil utilization features in order to filter out qualified walnut particular varieties for oil processing. By measuring seven phenotypic traits and nineteen physicochemical and nutritional quality traits of each variety, the coefficient of variation and correlation of each trait were calculated, and the traits closely related to oil quality were comprehensively evaluated using principal component analysis and cluster analysis. The findings revealed that there were relationships between walnut quality parameters. Among them, the kernel yield was found to be strongly inversely related to shell thickness (P
