We study the decays into six quarks of off-shell pairs of bosons produced in electron-positron annihilations, through the order in the strong coupling constant. We give explicit helicity amplitude formulae. We present numerical results in the context of phenomenological analyses of relevance at LEP2 and future Linear Colliders: such as MW determinations, New Physics and Higgs searches.
