We construct several N = 1 supersymmetric three-generation models with SU(3)×SU(2)×U(1)n gauge symmetry, obtained from orbifold compactification of the heterotic string in the presence of constant gauge-background fields. This Wilson-line mechanism also allows us to eliminate extra colour triplets which could mediate fast proton decay.
