  We obtain exact relations (valid to all orders in the coupling constant) for
the running gaugino mass in supersymmetric gauge theories, treating the soft
supersymmetry breaking effects in the linear approximation. If a supersymmetry
breaking squark (selectron) mass term is introduced, our relation connects the
renormalization group equation for this term with that for the gaugino mass.
Exact relations for the threshold effects in the gaugino masses are derived.
The key ingredients of our analysis is the use of the Wilsonean action and
holomorphy of this action with respect to relevant parameters.
