In this paper we write down consequences of exact and approximate invariance under the group G2, for the baryons, mesons, and resonances. We use the method of Weyl reflections and the Shmushkevich algorithm, previously applied to the group SU3, to derive electromagnetic mass and magnetic moment relationships, and also relationships between the one- to two-particle decay vertices (coupling constants). The assignment of multiplets is the usual one, using the singlet, the 7-fold, and the 14-fold representations of G2.
