  In the quark sector, Jarlskog rephasing invariant parameter $J_{CP}$ has
important implications for the CP violation as well as phase structure of the
quark mass matrices. In fact all CP violating effects in this sector are
proportional to the magnitude of the imaginary part of $J_{CP}$ . With the
observation of non-zero and large "reactor mixing angle", it is widely believed
that CP might be violated in the leptonic sector. In this context, we have
examined in detail the relationship of CP odd invariants for texture specific
mass matrices. In particular, we have calculated the predicted ranges of
Jarlskog rephasing invariant parameter and other weak basis invariants for all
the seven viable cases for texture two zero mass matrices.
