| Abstract: | Reyan No.4 King grass is a hybrid of Pennisetum purpureum and P.americana and was introduced from CIAT in 1984.The results from the variety testing show that the annual dry material production is 59670 kg/hm2,21.9% more than that of P.purpureum;The results from reginal trial show that the forage yield improved 11.3%-27.3% than that of P.Purpureum, and improved 13.3%-25.0% in production testing.The King grass has no head sprouting when cutting in the winter, and the time for utilization expended 5 months more than that of P.Purpureum. |
