  We study analytically and numerically the magnetotransport of strained
graphene in a Corbino geometry gating in the presence of an external
perpendicular magnetic field. The conductance of the Corbino disc of deformed
graphene with a uniaxial and an inhomogeneous strain is calculated by using the
Landauer-B\"{u}ttiker method. We show that the oscillation period of the
conductance as a function of the magnetic flux depends on uniaxial strain and
the conductance sharply drops along the direction of graphene stretching. The
conductance amplitude, on the other hand, can be manipulated by induced
pseudomagnetic flux. A valley polarized regime, caused by the inhomogeneous
strain, is obtained and in addition we find a wide energy interval in which the
system is fully valley polarized.
