Abstract: To screen out strawberry varieties with high comprehensive quality of fruit, and enrich the theoretical basis for strawberry cultivation, breeding, processing and utilization, 16 strawberry varieties and strains cultivated in Shanxi Province were collected as test materials to determine the fruit quality factors of appearance characters, nutrients and phenolic, and the comparison and evaluation were conducted with correlation analysis, principal component analysis and comprehensive scoring method of principal component. By principal component analysis, 9 quality factors of strawberry fruit was simplified to 3 types of principal components which could be named as phenol factor, appearance quality factor and nutritional factor respectively, and could reflect 81.0141% of the original data information. Among the 16 strawberry varieties and strains, ‘Tochiotome’,‘Akihime’and ’06- 2- 8’had high comprehensive quality of fruit while ‘Tochiotome’,‘Sweet Charlie’and‘05-1-5’had the opposite. Due to the differences between the results showed by mathematical analysis and intuitive analysis, it is necessary to use mathematical analysis to reduce subjectivity and unilateralism in fruit quality analysis of strawberry.
