We consider a system with electron-phonon interaction, antiferromagnetic fluctuations and disconnected open Fermi surfaces. The existence of odd-parity superconductivity in this circumstance is shown for the first time. If it is applied to the quasi-one-dimensional systems like the organic conductors we obtain spin-triplet superconductivity with nodeless gap. It is possible to extend our results to a quasi-two-dimensional case and to a three-dimensional case.
