Generalized Moore-Penrose inverses of morphisms with kernels are studied in this article.With the help of the invertibility of bordered morphisms,some new necessary and sufficient conditions for the existence and expressions of generalized Moore-Penrose inverses for morphisms are given.And some results on the Moore-Penrose inverse axe extended.
