With 1 figure and 1 tableAbstract A bulked segregant analysis using RAPD technique was carried out to identify molecular markers linked to apomixis in a Brachiaria humidicola F 1 population that segregated 1 : 1 for the mode of reproduction (apomixis and sexual). A marker related to the apo‐locus was found. Segregation data, together with this marker were used to generate a map of the region. This marker was located at 4.61 cM of the target locus, and it can be used in deploying marker‐assisted selection for mode of reproduction in the hybrid progenies of this species.
