Abstract
We have used the values of proper motions and distances for 21 radio pulsars with an age τ < 105 years and distances to the known supernova remnants (SNR) to search for the possible genetic link between these objects. It was shown that the distributions of pulsar velocities Vtrans for pulsars with τ < 105 years and τ > 105 years and mean values of Vtrans in these samples do not differ significantly. This means that the gravitational potential of Galaxy and the interstellar medium do not affect significantly the movement of pulsars. The estimates of angular distances between pulsars considered and possible native SNRs are given. For 20 pulsars with an age τ < 105 years the possible native SNRs were found. The associations with SNRs were indicated already for 13 of them in the ATNF catalog. For 7 radio pulsars such associations were found for the first time.
