Adaptation of new accessions of Panicum maximum to an acid Oxisol (pH 4.8, 90% AI saturation) was assessed over 3 years on 2 sites of contrasting soil texture at the Carimagua Research Station, in the Eastern Plains of Colombia. Twenty-seven lines, selected originally from a collection of 436 accessions, were evaluated along with 2 commercial cultivars as controls. Concurrently, a pot trial was established in the glasshouse at CIAT, Palmira Colombia to test the accessions for resistance to spittlebug (Aeneolamia reducta).
