The magnetoconductivity of a single graphene layer weakly modulated by a one-dimensional periodic potential is calculated. Pronounced Weiss oscillations periodic in the inverse magnetic field appear that are less damped by temperature as compared with the same oscillations found in a typical two-dimensional electron system with a standard parabolic energy spectrum.
