  In this talk, we discuss the SUSY-Yukawa sum rule, a relation among masses
and mixing angles of the third-generation squarks which follows directly from
the coupling relation responsible for canceling the quadratic divergence in the
Higgs mass. Radiative corrections modify the sum rule, introducing dependence
on a variety of SUSY parameters beyond the third-generation squark sector. If
some of those parameters are measured experimentally, a sharp prediction for
the sum rule is possible. We demonstrate this point with a quantitative study.
We also discuss the prospects for measuring the ingredients of the sum rule at
the LHC, and argue that a high-energy electron-positron collider such as the
ILC would be necessary to test the sum rule.
