For the \cN=1 SQCD with Nc colors and NcF<3N c flavors with small but nonzero current quark masses mQ eq 0, the dynamic scenario is considered, in which quarks form the diquark-condensate phase. This means that colorless chiral quark pairs condense coherently in the vacuum, \langle{\ov Q}Q\rangle eq 0, while quarks alone do not condense, \langle Q \rangle=\langle{\ov Q}\rangle=0, and therefore the color is confined. Such condensation of quarks results in the formation of dynamic constituent masses \mu_C\gg m_Q of quarks and the appearance of light ``pions'' (similarly to the case of QCD). The SQCD mass spectrum in this phase is described and compared with the Seiberg dual description. It is shown that the direct and dual theories are different (except, possibly, in the perturbative strictly superconformal regime).
