摘　　要：‘Tianlong 1’ is widely popularized and applied with good comprehensive characters and is also good receptor for genetic transformation. However, little is known about symbiotic nitrogen fixation of ‘Tianlong 1’. In this report, 10 soybean rhizobia from different areas were selected to perform symbiotic matching test with ‘Tianlong 1’ in chamber. Two aboveground indicators (fresh weight aboveground and plant height) and 4 underground indicators (length of root, number of nodules, dry weight of root nodules per plant and morphology of nodules) were measured and data were statistically analyzed. Results showed that ‘Tianlong 1’ was a broad-hosted soybean which has different symbiotic matching abilities with these 10 rhizobia. Bradyrhizobium japonicum has more advantages than Sinorhizobium fredii in promoting plant growth and nodulation. 113-2 and 5036 were high effective strains. 113-2 was regarded as the most effective rhizobium matching to ‘Tianlong 1’ due to geographical advantages and adaptability. This research will promote symbiotic fixation of ‘Tianlong 1’ in agricultural industry for the first time.
