| Abstract: | Panicum maximum cv.Reyan No.8was selected from a group of tropical forage varieties introduced from CIAT in1988and trial planted in1990.The preliminary results showed that P.maximum cv.Reyan No.8maintained such characteristics of Panicum species as high dry matter yield and good quality.It yielded22,500kg/hm 2 of fresh forage and contained7.738%(DM)of crude protein(CP).The flower period was30days later than that of P.maximum cv.Trichoglume,and the seed production was480.2kg/hm 2 ,87.8%higher than that of P.maximum cv.Tri choglume.It was tolerant to shade and infertile and acid soil and hence suitable for growing in tropical and sub-tropical regions in China. |
