We study the bottom quark to tau lepton mass ratio in a large class of non-SUSY SU (5) models. Our general analysis allows us to rule out most one-Higgs models which predict too large a value for the mass of the bottom quark. We then look at a particular two-Higgs model and show that the correct bottom quark mass can be achieved by setting the top quark Yukawa coupling close to its intermediate fixed point.
