M. L. de  aSelecting new Brachiaria humidicola hybrids for western Brazilian Amazonh[electronic resource]  c2013  aBrachiaria humidicola is a perennial and stoloniferous forage grass, with excellent adaptation to infertile soils and waterlogging. Producers in northern Brazil have become interested in this species, especially after the degradation of large areas of lowly permeable soils sown with B. brizantha cv. Marandu, which is highly intoler-ant of soil waterlogging (Andrade and Valentim 2006). However, since only 3 cultivars of B. humidicola are registered in Brazil (Mapa 2013), there is a need to de-velop new cultivars adapted to the range of environ-mental conditions experienced. Recently, Embrapa Beef Cattle obtained intraspecific hybrids of B. humidicola that need to be evaluated agronomically, aiming at sub-sequent grazing trials and future releases. The objective of this study was to evaluate and select apomictic and sexual hybrids of B. humidicola under the environmental conditions of the state of Acre, in western Brazilian Amazon.  aAcclimation  aEnvironmental factors  aForage grasses  aHybrids  aPastures  aAclimatação  aBrachiaria humidicola  aCapim Quicuio  aComportamento de variedade  aGramínea forrageira  aPastagem  aAclimatación  aAcre  aAmazonia Occidental  aAmazônia Ocidental  aBraquiária  aFactores ambientales  aHíbridos  aPastizales  aPastos forrajeros  aWestern Amazon1 aVALLE, C.
