Conteúdo: 	Brachiaria humidicola. also known as koronivia grass, is an African species well adapted to acid and poorly drained soils. It covers millions of hectares of pastures in tropical Latin America and it is used both for cattle and horses. Breeding was done for the first time in this species at Embrapa Beef Cattle, once a sexual tetraploid ecotype was identified in a collection of 58 accessions of B. humidicola introduced from eastern Africa. Controlled pollination in the greenhouse yielded hybrids from a cross between the sexual genotype and an apomictic accession. Since no emasculation was done, identification of hybrids vs. selfs became crucial thus RAPD markers were developed to discriminate hybrids precisely and early in the program.
