We explore the relationship between the extended radio and line emission for a radio‐loud quasar sample including both core‐dominated and lobe‐dominated quasars. A strong correlation is present between the extended radio and broad‐line emission. The core emission is also correlated with the broad‐line emission for core‐dominated quasars in the sample. The statistical behaviour of the core emission of lobe‐dominated quasars is rather different from that of core‐dominated quasars. The extended radio luminosity is a good tracer for jet power, while the core luminosity can only be a jet power tracer for core‐dominated quasars.
