The problem of nucleon-antinucleon (N anti N) annihilation is discussed in terms of the underlying quark-gluon dynamics of QCD. It is shown how recently observed selection rules exert a strong constraint on the effective quark-antiquark (Q anti Q) creation/destruction operator which enters in the annihilation process. The data on two meson modes suggest that a Q anti Q operator with one gluon quantum numbers is inadequate, and that a strong coupling approach to the treatment of the gluonic degrees of freedom is more appropriate. 25 refs., 1 fig.
