We have observed transitions from quasiperiodic regime to chaos in the periodically forced Brusselator. It takes place via kinking and folding of the originally smooth Poincare map which may be more generic as compared to the transition in circle mapping, where the quasiperiodic orbit looses smoothness globally. Now all the well-known "routes" to chaos have been shown to coexist in this mathematical model in different part of the parameter space. This is in agreement with experimental observations in some hydrodynamical systems where different routes to turbulence have been found in one and the same system under slightly different conditions.
