The description of all minimal classes in the partially ordered set {\frak{\cal L}}^{3}_{2} of closed classes of the three-valued logic that can be homomorphically mapped onto the two-valued logic is given.

Key words: three-valued logic, closed class, partially ordered set, homomorphism, minimal class.
