We study quark and electron EDMs generated by Yukawa couplings in supersymmetric models with different gauge groups, using the EDM properties under flavour transformations. In the MSSM (or if soft terms are mediated below the unification scale) the one loop contributions to the neutron EDM are smaller than in previous computations based on numerical methods, although increasing as tan^3\beta. A neutron EDM close to the experimental limits can be generated in SU(5), if tan\beta is large, throughdoi:10.1016/s0550-3213(97)00060-6 fatcat:kkja7sineffd3o6z6l3sox7bqq
