Quantum mechanics is the part of quantum physics devoted to the mechanics. Quantum field theory is the part of quantum theory devoted to fields. Quantum electrodynamics and quantum chromodynamics are subareas of quantum field theory. E.g. quantum electrodynamics studies electromagnetic and fermion fields.

Ok cool, so chromodynamics is similar to electrodynamics?

Yes are similar although quantum chromodynamics is more complex. In quantum electrodynamics you study electrons and photons and in quantum chromodynamics you study other particles as quarks and gluons. Surely you heard about quarks before.
