One-loop corrections to the top-quark decay width {Gamma}(t{r_arrow}W{sup +}b) from the pseudo Goldstone bosons (PGB{close_quote}s) in the multiscale walking technicolor model (MWTCM) are calculated. For the original MWTCM, the corrections are so large that the decay width is largely decreased. We show that if top-color is further introduced, the decay width is enhanced, and the corrections from PGB{close_quote}s in the top-color-assisted MWTCM may reach {minus}7{percent} for certain parameters in this model, which is expected to be detected in the future experiments. {copyright} {ital 1997} {ital The American Physical Society}
