Cenchrus spp. encompasses forage grasses that are especially important for drylands. Thus, information on their reproductive mechanism and genetic diversity is needed. The Active Germplasm Bank (AGB) of the Embrapa Semi?rido (Tropical semiarid research center) has 115 accessions of Cenchrus spp. that were not molecularly characterized. Therefore, the objective of this work was to evaluate the genetic diversity of Cenchrus spp. accessions in the AGB, and identify their reproductive mechanisms using DNA markers. Specific SCAR markers Q8H, UGT197, and PCAB10, in addition to the SCAR marker 4HS
