High-accuracy calculations of term energies and wavelengths of resonance lines in Ga-like ions have been performed as benchmarks in the request for accurate treatments of relativity, electron correction, and QED effects in multi-valence-electron systems. The calculated energy levels are in excellent agreement with the experimental results and the experimentally compiled energy values of the National Institute for Standards and Technology wherever available. The calculated values including core-valence correction are found to be in good agreement with other theoretical and experimental values for low-to medium-Z ions. On the basis of our calculations, some theoretical wavelengths for Ga-like Rb VII to Mo XII are also given. For higher-Z ions, computed wavelengths are compared well with the experimental results [E. Trabert, J. Clementson, P. Beiersdorfer, J. A. Santana, and Y. Ishikawa, Phys. Rev. A 82, 062519 (2010), I. N Draganic et al., J. Phys. B 44, 025001 (2011)].
