| Abstract: | Some introduced Panicum lines were evaluated to select suitable forage for tropic subtropic region in China. All 23 Pamicun lines grew well and could be over winter safely. The fresh weights of eight varieties were higher than that of the control. The average fresh yields of the first three top lines, CIAT 6966, CIAT 6172 and CIAT 6901 were 96 795.0 kg/hm 2 , 90 987.3 kg/hm 2 and 84 547.4 kg/hm 2 respectively, which were increased by 64.9% , 55.0% and 44.0% in comparison with the control. |
