  The complete set of Feynman rules for the rational part R of QCD corrections
in the MSSM are calculated at the one-loop level, which can be very useful in
the next-to-leading order calculations in supersymmetric models. Our results
are expressed in the 't Hooft-Veltman regularization scheme and in the Four
Dimensional Helicity scheme with non-anticommutating and anticommutating
$\gamma_5$ strategies.
