In order to select out miliaceum varieties with smut resistance for Qiqihar regions, resistance identification for ten miliaceum varieties in field was carried out. The results showed that the high resistance varieties were Nianfeng 3 ,Jinmi 7and Chimi 1 ,the yield of Chimi 1 was the highest ,Jinmi 7 took the second place,which both were significantly higher than other varieties. Resistance varieties were Nianfeng 7 and 962-083. Medium resistance varieties was Nianfeng 6, Medium susceptible varieties were Qishu 1 and Nianfeng 1 ;Susceptible varieties were Nianfeng 5 and Yanshu 8,Nianfeng 5 had the lowest yield for 2 456.2 kg. hm 2, the difference was significant with other varieties.
