Description
As part of the search for new forage germplasm options for clearedforest ecosystems in the humid tropics of South America, a smallplot clipping trial was conducted with 128 accessions of Centrosema macrocarpum near Pucallpa, Peru. Most of the accessions showed good adaptation to an acid ultisol with a high Al level (pH 4.4, 81% Al saturation), Considerable variation was detected among accessions for the agronomic attributes studied. On the basis of seasonal dry matter production and seed yield, the germplasm tested was classified into 8 cluster groups. All accessions proved to have a high level of pest and disease tolerance and most of them performed remarkably well during the low-rainfall period, Three groups of accessions have been identified which exhibited intermediate to high dry-matter yields in combination with good seed production.
