Abstract
We propose a theory of flavour based on Abelian horizontal gauge symmetries and modular invariances. We construct explicit supergravity models where the scale of the horizontal U(1) symmetry breaking is fixed by the Green-Schwarz mechanism for anomaly cancellation. The supersymmetric spectrum is obtained in terms of the U(1) charges which are determined by the Yukawa matrices.
