The correlation and path between the main economic characters and single-plant yield of 7 strawberry( Fragaria ananassa Duchesne) varieties were analyzed. The results showed that the coefficient of variation of yield components had the following order: number of fruits number of secondary fruits single-plant yield weight of secondary fruits average fruit weight number of primary fruits fruit transversal diameter fruit vertical diameter weight of primary fruits petiole diameter firmness.The correlation analysis revealed that the effects of 10 characters on single-plant yield had the following sequence: fruit transversal diameter weight of secondary fruits petiole diameter fruit vertical diameter number of fruits weight of primary fruits number of secondary fruits average fruit weight firmness number of primary fruits. The partial correlation analysis and path analysis consistently showed that the effect magnitude of main economic characters on single-plant yield could be arranged as follows: fruit transversal diameter average fruit weight number of primary fruits firmness number of fruits. The path analysis also indicated that fruit transversal diameter and firmness were the main factors affecting the yield per plant.
