Six varieties of Pennisetum purpureum,cv were compared to each other from 2006 to 2007,which were Pennisetum purpureum schumab cv.Red,(Pennisetum purpureum,cv. Mott)×(P.americanum×P.purureum)]cv.Guimu No.1,Pennisetum purpureum,cv. Mott,Pennisetum purpureum Schum cv.Taiwan,Pennisetum purpureum Schum.cv.Huanan and Pennisetum purpureum×P.typhoideum cv.Reyan.No.4.The results showed:all of them adapted to the environment of experiment area well.The fresh yield of Pennisetum purpureum Schum cv.Taiwan is the best,141 845.68 kg/hm~2;the next is Pennisetum purpureum×P.typhoideum cv,Reyan.No.4,187 798.85 kg/hm~2,(Pennisetum purpureum. cv.Mott)×(P.americanum×P.purureum)]cv.Guimu No.1,125 322.6 kg/hm~2, Pennisetum purpureum schumab cv.Red,119 179.58 kg/hm~2,the yield of which were respectively higher 81.87%,28.56%,16.92%,11.19% than that of the Pennisetum purpureum Schum.cv.Huanan,107 183.55 kg/hm~2,which is the control forage.As to other aspects,the Pennisetum purpureum,cv.Mott have more leaves and higher protein content, which make it suitable to feed small herbivorous,such as rabbits,fish and gooses,and so on. The better production,high yield and high nutrient contents of Pennisetum purpureum Schum cv.Taiwan and Pennisetum purpureum schumab cv.Red are as excellent as that of (Pennisetum purpureum,cv.Mott)×(P.americanum×P.purureum)]cv.Guimu No.1. Therefore,the Pennisetum purpureum Schum cv.Taiwan and Pennisetum purpureum schumab cv.Red have the potential to be a new kind of forage in the southern part of China,and which could be be applicated and expanded in the future.
