Objective To investigate the quality differences between Actinidia chinensis Planch in China’s main production areas and New Zealand Actinidia chinensis Planch, and make a comprehensive evaluation. Methods This study used Actinidia chinensis Planch fruits from the main production areas of China and New Zealand Actinidia chinensis as experimental materials, analyzed the phenotypic traits, nutritional composition and sensory evaluation indexes of Actinidia chinensis Planch fruits, and analyzed and comprehensively evaluated the Actinidia chinensis Planch fruits by using the method of systematic description, entropy weight-technique for order preference by similarity to ideal solution (TOPSIS) method was used to analyze and comprehensively evaluate Actinidia chinensis Planch. Results The quality indexes of Actinidia chinensis Planch fruits from different production areas differed significantly. The soluble solid content of red Actinidia chinensis Planch was the highest in Yunnan and Shaanxi, with 15.9 and 15.5%, respectively, and the lowest total acid content in Sichuan was0.86%, and the mean value of soluble sugar content was the highest in Yunnan and Sichuan, with 62.2% and 59.5%, respectively, Yunnan also had the highest mean fructose and glucose content (15.1% and 17.7%, respectively). The vitamin C content of greenheart Actinidia chinensis Planch was significantly higher than that of New Zealand for the Chinese production area; Hunan had the highest soluble solids content (18.0%), and the highest mean solid-acid ratios were found in Hunan (14.5) and Chongqing (14.4), the highest mean value of soluble sugar content was found in Chongqing (58.2%), but New Zealand had the highest mean values for fructose and glucose content, which were 14.2% and 16.4%, respectively. The yellow heart Actinidia chinensis Planch had the highest mean values of vitamin C, soluble solids, solid-acid ratio, soluble sugars, fructose and glucose content for New Zealand (0.89 mg/g, 16.7%, 14.3, 63.6%, 15.6% and 17.7%, respectively), but the sucrose content of Sichuan (3.73%) and Henan (3.61%) was higher than that of New Zealand. Conclusion The study show that there are quality differences between Actinidia chinensis Planch from China’s main production areas and New Zealand Actinidia chinensis Planch. The entropy weight-TOPSIS model show that the top two scores of red Actinidia chinensis Planch are the Hongyang Actinidia chinensis Planch from Yunnan and Sichuan, the top score of green Actinidia chinensis Planch is the CuiXiang Actinidia chinensis Planch from Shaanxi, and the Hayward Actinidia chinensis Planch from New Zealand ranked the 4th, while the top score of yellow Actinidia chinensis Planch is the Sunshine Golden Fruit Actinidia chinensis Planch from New Zealand, follow by the G3 Actinidia chinensis Planch from Sichuan and Yunnan. This study verify the validity of the multi-indicator evaluation through the three-dimensional correlation model of “sensory-composition-phenotype”, and provid methodological support for the construction of the Actinidia chinensis Planch quality evaluation system.
