Quark condensation with (n2−1) small-mass bosons requires the topological charge spectrum {ν} to depend on ratios of the quark masses which explicitly violate chiral SU(n)×SU(n) symmetry. General conditions are derived for non-integer ν and hence two vacua at θ=π (mod 2π), and for {ν} to be quantized in rational units. The results show that gluonic boundary conditions are influenced by quark dynamics.
