By means of solving the Bethe-Salpeter equation with the minimal perturbative kernel (ladder approximation) in the arbitrary covariant gauge, there was found a series of intercepts of meson Regge trajectories associated with colorless singularities of the four-quark Green function in SU(N{sub c}) quantum chromodynamics with massless quarks. The gauge and renorm-invariance of the result is grounded.
