Polarized heavy quarkonium productions in [Formula presented] decays are considered. We find that polarizations of the produced quarkonia are independent of that of the parent [Formula presented] provided that one considers the energy distribution or the total production rate. Produced [Formula presented]’s via the color-octet and the color-singlet mechanisms are expected to be 19% and 29% longitudinally polarized, respectively. The energy dependence of [Formula presented] [Formula presented] is very sensitive to the production mechanism, and, therefore, the measurement of [Formula presented] will be an independent probe of the color-octet mechanism.
