An analysis is made of the group properties of the weak hadronic currents constructed from the quarks in the SU (n) schemes for n between 3 and 6. It is shown that the absence of neutral currents which change the internal quantum numbers (strangeness, charm, etc.) can be ensured in the framework of unitary symmetry with an even number of quarks by an appropriate choice of the initial weak current in a given multiplet. The proposed method of constructing the weak hadronic currents in the unitary symmetry schemes provides a completely natural way of determining the general form of the current with the correct right-handed and left-handed components. The method can readily be generalized to the case of arbitrary n. The physical consequences for the SU (6) quark scheme are briefly discussed.
