Preliminary evaluation of Brachiaria humidicola hybrids
Brazil has about 100 million hectares of cultivated pastures,of which about 85％ are covered with grasses from the Brachiaria genus.B. humidicola, also known as koronivia grass,is an African species well adapted to acid and poorly drained soils and of widespread use in millions of hectares of pastures in tropical Latin America.Breeding was only achieved recently at Embrapa Beef Cattle, using a sexual tetraploid ecotype crossed to an apomict.Controlled pollination in the greenhouse was used and progeny obtained was evaluated to determine mode of reproduction and the inheritance of apomixis in this species.
