Conteúdo: | Progenies of intervarietal hybrid stylos (Stylosanthes guianensis var.vulgaris  x  S.guianensis var. Pauciflora) with mid-season maturity date (eariy-and mid-June), high dry matter and seed yieids have been identified at the National Beef Cattle Research Center (CNPGC), Campo Grande, MS, Brazil. Dry matter yields of the best selections were comparable to those of the late-fiowering control, cv. Mineirao Severai mid-season hybrids produced 150 to 200 kg/ha of seed-in- pod and a singie plant seiection yieided in excess of 300 kg/ha. The high degree of resistance to anthracnose observed in the advanced generations is attributed to the immense genetic diversity of these heterogeneous popuiations which restricted the development of this highiy variabie pathogen. Stabiiity of disease resistance of superior mid-season maturity types and their adaptation to a wider range of ecological situations have yet to be assessed in multilacationa trials. Grazing productivity experiments are required to deternine animal production and persistency of the selected materials.
