  The goal of this work is to determine the nature of the relation between
morphology and accretion mode in radio galaxies, including environmental
parameters. The CoNFIG extended catalogue (improved by new Ks-band
identifications and estimated redshifts from UKIDSS, and spectral index
measurements from new GMRT observations) is used to select a sub-sample of 206
radio galaxies with z<0.3 over a wide range of radio luminosity, which are
morphology-classified using the Fanaroff-Riley (FR) classification of extended
radio sources. For each galaxy, spectroscopic data are retrieved to determine
the high/low excitation status of the source, related to its accretion mode.
Environmental factors, such as the host galaxy luminosity and a richness factor
are also computed, generally using SDSS data.
