The -dual of a vector-valued sequence space is defined and studied. We show that if an -valued sequence space is a BK-space having AK property, then the dual space of and its -dual are isometrically isomorphic. We also give characterizations of -dual of vector-valued sequence spaces of Maddox , , , and .
