We use a sample of SEGUE G-dwarfs to constrain the local behaviour of the rotation curve of the Milky Way. We find the mean galactocentric rotation velocity of the stars, correct for the asymmetric drift and the vertical gradient of the circular velocity, and construct the rotation curve at the galactocentric radii 7 to 10 kpc. The rotation curve appears flat, with no significant dips in the considered range. Then we use TGAS sample with Gaia parallaxes to constrain the local slope of the rotation curve.
