Objective: To study on the intraspecific variation of Forsythiae Fructus

clarify the morphological characteristics

quality and yield in different habits and different fruit types

and lay the foundation for better development

utilization and protection of germplasm resources as well as breeding of fine varieties of Forsythiae Fructus. Method: The morphological characteristics of different fruit types were observed

and their length

width and yield were measured as basis for determining the type of fruit.The contents of chemical components in different fruit types were measured by using high performance liquid chromatography (HPLC)and the comprehensive evaluation was then carried out. Result: Upon investigation of intraspecific variation

the fruits of Forsythiae Fructus were classified into long oval

oval

spindle

elongated and round types. The economic indexesand properties of these different fruit types were analyzed and described. The results showed that the yield of spindle shape was highest

so it was among the high yield types.The phillyrin

forsythiaside A

ethanol soluble extraction and weight per 100 fruits in agricultural economic index of different fruit types were measured

and a comprehensive evaluation of different sources of Forsythiae Fructus was carried out by the method of principal component analysis.The comprehensive evaluation of spindle shape was better. Conclusion: This experiment could lay foundation for the breeding of new varieties and the quality improvement of Forsythiae Fructus.
