We study analytically and numerically the magnetotransport of a strained graphene in a Corbino geometry gating in the presence of an external perpendicular magnetic eld. The conductance of the Corbino disc of deformed graphene with a uniaxial and an inhomogeneous strain is calculated
by using the Landauer-Buttiker method. We show that the oscillation period of the conductance as a function of the magnetic ux depends on strain and the conductance amplitude sharply drop along the direction of graphene stretching. A valley polarized regime, caused by inhomogeneous strain, is obtained and in addition we nd a wide energy interval in which the system is fully valley polarized.
