In this talk rst of all we reveiw some results concerning (generalized) Jordan derivationson triangular ring. Then under some conditions we shall prove that every generalized Jor-dan derivation associate with Hochschild ۲-cocycle a on a triangular ring is a generalizedderivation associate with Hochschild ۲-cocycle a .
