  We give some remarks on the $\bar n p$-partial branching ratios in flight at
low momenta of antineutron, measured by OBELIX collaboration. The comparison is
made to the known branching ratios from the $p \bar p$-atomic states. The
branching ratio for the reaction $\bar n p \to \pi^+\pi^0$ is found to be
suppressed in comparison to what follows from the $ p \bar p$-data. It is also
shown, that there is no so called dynamic I=0-amplitude suppression for the
process $N\bar N \to K\bar K$.
