The central black hole masses of a sample of radio‐loud quasars are estimated by using the data of H β linewidth and the optical continuum luminosity. The vast majority of the quasars in this sample have black hole masses larger than 10 8 M ⊙ , while a few quasars may contain relatively smaller black holes. We found a significant anti‐correlation between the radio loudness and the central black hole mass. It might imply that the jet formation is governed by the black hole mass.
