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