Using an earlier result that for a rough vector field on the circle there exists a complete system of invariants relative to a smooth conjugation the author gives - in terms of these invariants - criteria for versality of a deformation of such a vector field. More precisely, it is proved that an infinitesimal versal deformation is a versal deformation, and a criterion for infinitesimal versality is given.
