The growth characteristic and quality analysis of 4 Brachiaria decumbens varieties were conducted for 3 years.The results showed that all varieties grew normally in southern Fujian.The blooming stage of Reyan No.3 and Reyan No.6 was in the early and middle of June.The blooming stage of 2 hybrid varieties was later about 2 months than Reyan No.6.The annual fresh yield of Hybrid Mulato 1 was the highest and it was significantly different from that of Reyan No.6(P0.01).The crude protein content of Hybrid Mulato 1 was the hightest(9.38%) in tillering stage.The crude fat and calcium contents of Reyan No.6 were the highest.The relative feeding value of all varieties were around 100%.It suggested that Hybrid Mulato 1 could be widely extended in southern Fujian.
