In this paper, we study \F vector subdifferentials of vector-valued functions in normed spaces which reduce to the known ones of extended-real-valued functions. We establish relations between two kinds of Fréchet vector subdifferentials and between subdifferential and coderivative; some of them improve the existing relations for extended-real-valued functions. Finally, sum and chain rules among others for Fréchet subdifferentials of vector-valued functions are formulated and verified. Many examples are provided.
