Abstract: Panicum maximum cv.Reyan No.9 is selected from a group of tropical forage varieties introduced from CIAT in 1988 and began to trial in 1990. The preliminary results showed that P.maximum cv.Reyan No.9 maintained its genus characteristics of high dry matter yield and quality. Its dry forage yield was 18000kg/hm² and seed production was 495.8kg/hm²,improved 40% and 93.9% than P.maximum cv.Trichoglume respectively,crude protein (CP) contents was 7.90% (DM); acid-infertile tolerance、shade tolerance、low temperature、dry tolerance improved significantly and adapted to plant in tropical and sub-tropical regions especially release in South-China.
