The one-loop induced Z{yields}gg{gamma} and Z{sup '}{yields}gg{gamma} decays are studied within the context of the minimal 331 model, which predicts the existence of new gauge bosons and three exotic quarks. It is found that the Z{yields}gg{gamma} decay is insensitive to the presence of the exotic quarks, as it is essentially governed by the first two families of known quarks. As to the Z{sup '}{yields}gg{gamma} decay, it is found that the exotic quark contribution dominates and that for a heavy Z{sup '} boson it leads to a {gamma}(Z{sup '}{yields}gg{gamma}) that is more than 1 order of magnitude larger than that associated with {gamma}(Z{sup '}{yields}ggg). This result may be used to distinguish a new neutral Z{sup '} boson from those models that do not introduce exotic quarks.
