The objective of this field experiment was to study the difference among the four varieties of Chinese milk vetch in the three double cropping rice areas，hoping to select the optimum variety for different areas.The results showed that the childbearing period of Xiangfei and Yijiang were shorter than Ningbo and Nanchang in the three different areas.The fresh grass yield of different varieties in the same area were discrepancy，the yield of Ningbo were highest in Chongyang, arrived at 3827 t/hm2,the yield of Xiangfei were highest in Xishui, arrived at 2278 t/hm2,and the yield of Nanchang were highest in Zhijiang,arrived at 4692 t/hm2.The nutrients accumulation were different in the three areas.The N，P，C accumulation of Ningbo and Nanchang were higher in Chongyang，the N，P，K，C accumulation of Xiangfei and Yijiang were higher in Xishui，and the N，P，K，C accumulation of Yijiang and Nanchang were higher in Zhijiang.In conclusion，taking the childbearing period，the fresh grass yield，and the nutrients accumulation into consideration，Nanchang and Ningbo were the best variety in the Southeastern low mountain and hilly area，Xiangfei and Yijiang were the best variety in the eastern hilly area，Yijiang and Nanchang were the best variety in the Jianghan Plain.
