In this paper vector valued functions under V- ρ -invexity functions are derived which is generalization of the concept of V – invexity and (β, η) invexity and establish sufficient optimality condition and weak vector saddle point theorems and also duality results for non-smooth multiobjective fractional programming problems are derived.
