In this paper we answer a question posed by Ju. I. Manin: For which quasicharacters does there exist a generalized Neron pairing? It turns out that the quasicharacter must trivialize some explicitly described group of roots of unity. In addition, we establish in this paper a connection between generalized Neron pairings and the biextensions of Mumford.
