  We investigate the mesonic condensation in isospin matter under rotation.
Using the two-flavor NJL effective model under the presence of global rotation,
we demonstrate two important effects of the rotation on its phase structure: a
rotational suppression of the scalar-channel condensates, in particular the
pion condensation region; and a rotational enhancement of the rho condensation
region with vector-channel condensate. A new phase diagram for isospin matter
under rotation is mapped out on the $\omega-\mu_I$ plane where three
distinctive phases, corresponding to $\sigma$, $\pi$, $\rho$ dominated regions
respectively, are separated by a second-order line at low isospin chemical
potential and a first-order line at high rotation which are further connected
at a tri-critical point.
