The tiller number, survival rate and disease and pest resistance all show the production potential, Comprehensive assessment was the best. The grass belongs to Panicum genus with the aspect of, survival rate growth vigor, plant height, dry matter yield all show the good adaptability. The grass belongs to Setaria is just common except Penisetum purpureum. The grass subordinateto Paspalum genus show comparatively bad, except Paspalum atratum cv. Reyan No.11.
