Pecan had been introduced into China for over one hundred years and had raised great attentions as a woody oil crop these years, but the detailed nut qualities of pecan cultivars grown in China had not been evaluated before. To access the adaptabilities of different pecan cultivars after introduce and for future utilization of these cultivars, the pecan nut quality had been evaluated in this article. Both physical and chemical nut quality traits were evaluated on Chinese-grown pecan cultivars, including nut weight, nut shape, shell thickness, kernel, lipid, fatty acid content, tocopherol content, antioxidant capacities of lipids, phenolics contents and their antioxidant capacities. Great variability existed among different cultivars in most of the nut quality traits. After introduced, physical traits changed in different ways, which suggested that cultivars have different adaptabilities. Cultivars 'Desirable', 'Western' or 'Kanza' are high in oleic acid, while cultivar 'Pawnee' is high in γ-tocopherol. Cultivar 'Mahan' had significant high values of total phenolic content (TPC), condensed tannins (CT), total flavonoid content (TFC), ellagic acid content and antioxidant capacity of defatted kernel compared to other cultivars, which made it an suitable material for further study of phenolics in pecan. This article provided detailed analyses of the nut qualities of Chinese-grown pecan cultivars for the first time, which can be useful for future studies.
