Is there anything wrong with

graph=Graph[ cities, DeleteDuplicates[#] ] &/@ edges

or should it be required to only pick *some* of the edges and not all

graph=Graph[ cities, DeleteDuplicates[#] ] &/@ edges[[;;imax]]

graph=Graph[ cities, DeleteDuplicates[#] ] &/@ edges[[imin;;imax]]

graph=Graph[ cities, DeleteDuplicates[#] ] &/@ edges[[{somi}]]
