In this paper, we carry out a numerical and systematic analysis of the neutrino mass textures, which contain one vanishing minor and equality between two cofactors. Among 60 logically possible textures, only eight of them are excluded for both the normal and inverted hierarchy by the current experimental data at 3σ level. We also demonstrate that the future long-baseline neutrino oscillation experiments, especially for the measurement of the θ 23 mixing angle, will play an important role in the model selection. The phenomenological implications from neutrinoless double-beta decay and the cosmology observation are also examined. A discussion of the flavor symmetry realization of the textures is also given.
