Abstract: This experiment has used 10 strawberry varieties as test materials. By measuring 19 indicators of fruit quality and nutritional quality of each variety, a comprehensive comparison was made to provide reference for strawberry production and future strawberry breeding in Tianjin. The test results showed that different varieties performed differently in terms of quality indicators. The cluster analysis method was used to classify the ten varieties according to the correlation of multiple quality traits, and the ten varieties were clustered into four categories. Among them, phenols of the first type is higher, including ‘Benihoppe' ‘Sweet Charlie' and ‘Toyonoka'; the second type highlights the fruit taste and single fruit weight, and gathers ‘Suizhu' ‘Ssanta' ‘Sagahonoka' ‘Xuemei' and ‘Akihimei'; the third type is ‘Allstar' and it can be used as a processed variety; the fourth category is rich in antioxidant including first love of ‘Hatsukoi'. The test results provide theoretical basis for strawberry quality breeding.
