  Planar equivalence between the large $N$ limits of ${\cal N}=1$ Super
Yang-Mills (SYM) theory and a variant of QCD with fermions in the antisymmetric
representation is a powerful tool to obtain analytic non-perturbative results
in QCD itself. In particular, it allows the quark condensate for $N=3$ QCD with
quarks in the fundamental representation to be inferred from exact calculations
of the gluino condensate in ${\cal N}=1$ SYM. In this paper, we review and
refine our earlier predictions for the quark condensate in QCD with a general
number $n_f$ of flavours and confront these with lattice results.
