The contributions of G'-boson predicted by the chiral color symmetry of quarks to the cross section [Formula: see text] and to the forward–backward asymmetry [Formula: see text] of [Formula: see text] production at the Tevatron are calculated with account of the difference of the strengths of the [Formula: see text] and [Formula: see text] interactions. The results are analyzed in dependence on two free parameters of the model, the mixing angle θ G and G' mass m G' . The G'-boson contributions to [Formula: see text] and [Formula: see text] are shown to be consistent with the Tevatron data on [Formula: see text] and [Formula: see text], the allowed region in the m G' - θ G plane is discussed and around m G' = 1.2 TeV , θ G = 14° the region of 1σ consistency is found.
