Scientific paper

We review recent developments for the calculation of Born amplitudes in QCD.
This includes the computation of gluon helicity amplitudes from MHV vertices
and an approach based on scalar propagators and a set of three- and four-valent
vertices. The latter easily generalizes to amplitudes with any number of quark
pairs. The quarks may be massless or massive.
