  This is a summary of the latest results of the DELPHI Collaboration on the
properties of identified quark and gluon jets. It covers the measurement of the
fragmentation functions of gluons and quarks and their scaling violation
behaviour as well as an analysis of the scale dependence of the multiplicities
in gluon and quark jets. Further, a precision measurement of CA/CF from the
multiplicities in symmetric three jet events is discussed.
