Abstract
Corrections to the branching ratio BR(B --> X(s)gamma) from technipions and top pions appeared in technicolor models are investigated. We found that: (a) the multiscale walking technicolor model is ruled out since it is confl ict with the CLEO data; (b) the top color-assisted technicolor model is con sistent with the CLEO data of BR(B --> X(s)gamma) for a certain range of pa rameters.
