A reliable estimate of the ^45V(p,γ) reaction rate is necessary in order to reduce a large uncertainty in the production of ^44Ti in core collapse supernovae. We performed a theoretical analysis of the astrophysical factors and reaction rates including resonances in ^46Cr associated with the analog states in ^46Ti. Full fp shell model calculations are performed to predict positive parity states in ^46Ti situated in the Gamow window, which have a significant proton spectroscopic factor. The uncertainty of the reaction rate associated with electric dipole gamma decays to the negative parity low-lying states is also discussed.
