An agronomic evaluation of the tropical forage legume Calopogonium mucunoides Desv., was made by growing 215 accessions for two levels of fertility on a red-yellow latosol in the Brazilian Cerrado. Annual dry matter yield (DMY) for the 12 cluster ranged from 1-3.6 t ha e-1, the highest being in clusters 1,3,7 and 9. These four clusters contained 47 accessions (22% of the collection), with medium-low seed yield. Groups 1,3 and 6 with clusters 11,10,4,5,8,2 and 6 were 56% o the collection, with intermediate DMY and variable seed yield, ranging from high to low. Seed yield during the first year was high only in group one (clusters 10 and 11) which was only 10% of the collection. The collection presented two other important differences. Leaflets varied in size (normal, as the commercial C. mucunoides cv. Comúm, and small) and in the number of hairs mm e-2. Also, a negative relationship between the degree of pilosity and in vitro dry matter digestibility was found. Hairs were impregnated with lignin and cutin, both of which impede digestibility of intact tissue. Seventeen accessions were selected for further evaluation in larger plots. Two accesions, CIAT 822 and 20709, were outstanding for their leaf retention during the dry season in the Cerrado ecosystem. |
