[Objective]In order to evaluate production performance of the new varieties of Onobrychis viciaefolia,and to provide basic data for their demonstrating and promoting as well as variety certification.[Methods]Three new varieties of Onobrychis viciaefolia (ND056-1,ND056-2 and ND056-3) cultivated by Xinjiang Agricultural University were used as experimental materials,and the Qitai variety as a control(CK),the production performance was comprehensively evaluated by observing indicators such as growth period,plant height,dry-fresh ratio,stem-leaf ratio,fresh grass yield,and hay yield.[Results]The results showed that there was no difference in the phenological period of the four varieties. The average plant height of ND056-3 was the highest (104.2 cm),followed by ND056-2 (104.13 cm) and that of CK was the lowest (103.07 cm). The dry-fresh ratio of ND056-1 was the highest (30.15％),which was 1.22 times than that of the control,and ND056-2 was the lowest (23.73％),0.96 times than the control. The leaf-stem ratio of ND056-3 was highest with 1.2266,followed by ND056-2 with 0.9918,which were 1.1 and 1.38 times than the control,respectively. The highest of annual fresh grass yield was the ND056-3 with 70.58 t/hm2,followed by ND056-1 with 66.25 t/hm2,which were 1.247 and 1.170 times than the control. The highest annual hay yield was the ND056-1 with 19.89 t/hm2,followed by ND056-3 with 19.32 t/hm2,which were 1.30 and 1.27 times that of the control,respectively.[Conclusion]As a conclusion,the ND056-3 was suitable for use as fresh grass,while ND056-1 as hay.
