Abstract: The paper aims to provide reference for introduction and cultivation of Carya illinoensis. We carried out the phenological periods observation, analyzed the appearance quality and inclusion contents, and evaluated the varieties differences of 7 introduced Carya illinoensis varieties in Hubei. The results showed that: (1) the 7 varieties all could complete the growth cycle, which varied from 218 to 237 days, the varieties of ‘Shaoxing’,‘Shawnee’and‘Jinhua’might cross-fertilize; (2) among the 7 varieties, ‘Baker’ had the lowest nut weight and thinnest nut shell, which were 3.19 g and 0.65 mm, respectively; and‘Jinhua’had the highest nut weight and the thickest nut shell, 9.66 g and 0.95 mm, respectively;‘Choctaw’and‘Jinhua’had the highest and lowest kernel rate of nut, 56.01% and 41.90%, respectively;‘Shawnee’and‘Jinhua’had the maximum and minimum nuclear shape index of nut, 2.19 and 1.60, respectively; (3) among the 7 varieties, the maximum and minimum crude fat content of nut were found in ‘Pawnee’ , ‘Caddo’ , 76% and 67.52% , respectively; and the protein and total sugar content of‘Caddo’were the highest of 11.52% and 9.05% , respectively; the lowest protein (8.31%) and total sugar content (6.17%) of nut were found in‘Shawnee’and ‘Jinhua’, respectively.
