We establish the quantum theory of the one-mode micromaser injected by ultracold V-type three-level atoms with atomic coherence, and discuss the properties of the emission probability, the photon statistics, the spectrum and the velocity selection. We find the following results. There are two sets of peaks in the plot of the emission probability versus the cavity length. The injected atomic coherence can deeply affect the values of the two sets of peaks and the unresonant platform.
