The Guliev hypothesis on transneptunian objects as sources of comets is analyzed. We performed a numerical integration of the equations of motion for 137 near-parabolic comets over a time interval of 5000 years. No interactions of 78 comets with the transneptunian object 2003 UB 313 are revealed: the comets did not near it for a distance less than 3 AU. It is shown that 59 comets which are candidates to Pluto's family approached Pluto for a distance more than 0.7AU. The following conclusion can be reached: the Guliev hypothesis on transneptunian objects as sources of comets broke down.
