Origin of a polyploid accession of Brachiaria humidicola (Poaceae: Panicoideae: Paniceae)

open access: yesGenetics and Molecular Research, 2009
Brachiaria humidicola, a species adapted to poorly drained and infertile acid soils, is widely used throughout the tropics. Cytological characterization of 54 accessions of B. humidicola for breeding purposes revealed 2n = 36, 42, and 54 chromosomes. One accession (H030), with 2n = 42 chromosomes, showed a different meiotic behavior. In most accessions
