Flavor structure of soft supersymmetry breaking parameters is studied in a
certain type of effective supergravity theory derived from moduli/dilaton
dominated supersymmetry breaking. Some interesting sum rules for soft scalar
masses are presented. They constrain their flavor structure and predict some
interesting patterns appeared in soft scalar masses in the non-universal case.
We also study the alignment phenomena in the flavor space of soft breaking
parameters due to Yukawa couplings and discuss their phenomenological
consequences.Comment: 19 pages, latex, a version published in Phys. Rev. D, minor
