We calculate the corrections of extended technicolor (ETC) interactions to the asymmetry parameter ALR and the polarized parameters pLt, PtR of the process e+ e-→tt in topcolor-assisted multiscale technicolor model. Our results show that the ETC effect on PtR is negligibly small which can be safely ignored, and the ETC effect on ALR may be testable at high energy e+e- linear collider (LC). For 0.03 ≤ε≤ 0.1, 500 GeV ≤ s ≤ 800 GeV, the relative correction of PtL is in the range of 15% ≤δPtL/PtL,SM ≤ 39%, which will certainly be detected at the LC experiments (for example TESLA).``
