  We have carried out a search for gas-rich dwarf galaxies that have lower
rotation velocities in their outskirts than MOdified Newtonian Dynamics (MOND)
predicts, so that the amplitude of their rotation curves cannot be fitted by
arbitrarily increasing the mass-to-light ratio of the stellar component or by
assuming additional undetected matter. With presently available data, the
gas-rich galaxies UGC 4173, Holmberg II, ESO 245-G05, NGC 4861 and ESO 364-G029
deviate most from MOND predictions and, thereby, provide a sample of promising
targets in testing the MOND framework. In the case of Holmberg II and NGC 4861,
we find that their rotation curves are probably inconsistent with MOND, unless
their inclinations and distances differ significantly from the nominal ones.
The galaxy ESO 364-G029 is a promising target because its baryonic mass and
rotation curve are similar to Holmberg II but presents a higher inclination.
Deeper photometric and HI observations of ESO 364-G029, together with further
decreasing systematic uncertainties, may provide a strong test to MOND.
