The dynamical scenario is considered for N=1 SQCD, with N_c colors and
N_c<N_F<3N_c flavors with small but nonzero current quark masses m_Q\neq 0, in
which quarks form the diquark-condensate phase. This means that colorless
chiral quark pairs condense coherently in the vacuum, \neq 0, while
quarks alone don't condense, ==0, so that the color is confined.
Such condensation of quarks results in formation of dynamical constituent
masses \mu_C \gg m_Q of quarks and appearance of light "pions" (similarly to
QCD). The mass spectrum of SQCD in this phase is described and comparison with
the Seiberg dual description is performed. It is shown that the direct and dual
theories are different (except, possibly, for the perturbative strictly
superconformal regime).Comment: 31 pages; text improved; corrections in sections 5,8; appendix added
