OBJECTIVE: To transfer the effective elements of Bupleurum scorzonerifolium into carrot, and provide theoretical data for the exploitation, improvement and selection of the germplasm of Chinese medicinal plants. METHOD: The protoplasta of Bupleurum scorzonerifolium irradiated by ultraviolet light (UV) at an intensity of 300 microW.(cm2)-1 for 0, 1, 2 min respectively were fused with those of carrot Fisch by PEG method. The regenerated clones, derived form a single fused cell, were examined for their hybrid nature by phenotype and Esterase isoenzyme analysis. RESULT: Nine clones were identified as the somatic hybrids between B. scorzonerifolium and carrot. CONCLUSION: This provides a firm foundation for the further analysis of the main active components saikosaponin of somatic hybrids and the screening out of high-medicine-content hybrid cell lines.
