摘要： A brachiaria breeding program initiated in 1988 at CI AT (Centro Internacional de Agricultura Tropical) combined desirable attributes found in accessions of Brachiaria hrizantha and B. decumbens. Three apomictic hybrids have been released (cvs. Mulato, Mulato II and Cayman). Mulato showed agronomic potential but seed yields were low. Trials in Central America demonstrated the superiority of Mulato II, a vigorous grass with very deep and branched roots, giving it excellent drought resistance in the Brazilian Cenado and Mexico. Mulato II has excellent nutritional value. Following trials in Mexico and Thailand, evaluating 155 new hybrids for 7 years, cv. Cayman was released due to strong waterlogging tolerance. Research conducted on growth, quality, production, persistence and seed yields of brachiaria hybrids in Asia, Central America and Africa from 2003 to 2013 is summarized in the paper.
