Conteúdo: 	Hybrid stylos (Stylosanthes guianensis var. vulgaris x var.pauciflora) with durable, quantitative resistance to anthracnose, mid-season haverst maturity date (early-July), high DM and seed yields have been selected at the Embrapa Beef Cattle Research Center. Campo Grande, Brazil. The hybrids displayed improved forage traits in Brazil, the native habitat and major center of diversity of the species and its pathogen, as well as in vastly different ecosystems. Dry forage yields and anthracnose resistance of superior selections and their composites were  equal, in some instances significantly better, than those of cv. Mineirão in multilocational trials situated in the Cerrados form lat. 6 S to lat 20 S. Selected hybrids perfomed well in comparison with the highly successful CIAT 84 (cv. Reyan II) on Haiman Island. China. Composites have also good promise in seed multiplication plots in Queensland, Australia. A positive attribute of composite hybrids is their great genetic diversity in contrast to pure-line cultivars with a realatively narrow genetic base. These truly tropical forms of stylo are best adapted to regions with>1500mm average annual rainfall.
