  In this paper, we consider the quantum correlations, coherence and
entanglement, in neutrino oscillation. We find that the $l_{1}$-norm as a
coherence measure is equal to sum of the three possible concurrences for
measuring the entanglement among different flavor modes which were calculated
in the paper by (M. Blasone et al., Europhys. Lett., {\bf 112}, 20007). Our
result shows that the origin of the flavor entanglement in neutrino oscillation
is the same as that of quantum coherence. Furthermore, in the wave packet
framework, the variation of $l_{1}$-norm is investigated by varying the wave
packet width $\sigma_{x}$. As it is expected the amount of coherence increases
by $\sigma_{x}$ due to the increase in the overlapping of the mass eigenstates.
