The yield, plant form and fruit quality characters of strawberry grown at various period in China were evaluated in a randomized block design with 3 replications. The results were as follows: new cultivars grown in 1990’s were superior in yield per plant, averrage fruit weight, fruit soluble solid content and firmness. No significant difference was found in fruit sugar, acid and vitamin C content of cultivars grown at various peried. The plant height changed from short to high and to medium, and the petiole diameter increased in accord with the vield per plant.
