In the framework of one generation technicolor model we calculated the virtual effects from heavy PG bosons to the Zb $$($) over bar b vertex. Within parameter space the largest reduction from the charged PGB's and top quark to the partial width Gamma(b) was 71 MeV while the maximum correction to the branching ratio R(b) was about 14%. From the comparison of theoretical predictions with the corresponding data we are able to put an ''primary'' upper bound on the mass of P-8(+/-): M(P2) < 280 GeV for given M(t) = 200 GeV.
