The results of the study of variations of total-to-selective extinction RV near the Galactic plane (-12° ≤ b ≤+12°) are presented. It is shown that variations of RV range from 1.9 to 3.4 and it is not possible to determine its typical value for the Galaxy. The conclusion that variations of the parameter RV closely correlates with the distribution of interstellar extinction is confirmed.
