  We construct supergravity plus branes solutions, which we argue to be related
to 4d N=1 SQCD with a quartic superpotential. The geometries depend on the
ratio Nf/Nc which can be kept of order one, present a good singularity at the
origin and are weakly curved elsewhere. We support our field theory
interpretation by studying a variety of features like R-symmetry breaking,
instantons, Seiberg duality, Wilson loops and pair creation, running of
couplings and domain walls. In a second part of this paper, we address a
different problem: the analysis of the interesting physics of different members
of a family of supergravity solutions dual to (unflavored) N=1 SYM plus some UV
completion.
