  A new concept of generation of the cosmological baryon excess along with the
cold dark matter (CDM) in the Universe is proposed and corresponding scenarios
are outlined. Possible realizations of the idea in the framework of
supersymmetric models are considered and constraints (predictions) on masses of
sparticles compatible with the viability of the scenario are derived. Mulitiple
predictions might be extracted from the concept. In particular, we predict a
quite natural existence of a charge asymmetric component of CDM. A $\sim
10^{-2}$ part of CDM might exist in the form of electrically charged relic
particles with masses $m \simeq 1$ TeV. They are negatively charged and are
dresses by protons. This conjecture provides a rich field of immediate search
for these particles. The charge symmetric component of CDM might be represented
by very light, $m \approx 2$ GeV, very weakly interacting particles like
right-handed sneutrinos ( so recoils expected are rare and have quite small
energies, $E_{recoil} \sim 1$ KeV.) This leads by the way to prediction of
long-living (charged) sparticles. Some new experimental proposals for
non-traditional search of cold dark matter particles are mentioned.
