Conteúdo: 	Progenies of intervarietal hybrid stylos (Stylosanthes guianensis var vulgaris x S.guianensis var. pauciflora) with mid-season maturity date (earlv-and mid-June), high dry matter and seed yields 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-flowering control, cv. Mineirão. Several mid-season hybrids produced 150 to 200 kg/ha of seed-inpod and a single plant selection yilded in excess of 300 kg/ha. The high degree of resistance to anthacnose observed in the advanced generations is attributed to the immense genetic diversity of these heterogeneous populations which restriccted the development of thid highly variable pathogen. Stability 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 multilocational trials. Grazing productivity experiments are required to determine animal production and persistency of the selected materials.
