We study large N dualities for a class of N = 1 theories realized on type IIB D5 branes wrapping two-cycles of local Calabi-Yau three-fold which is obtained from resolving orbifolded conifolds or as effective field theories on D4 branes in type IIA brane configurations. The field theory is N = 1 supersymmetric ∏ U (Nij) Yang-Mills gauge theory. Strong coupling effects are analyzed in the deformed geometry. We propose closed string duality via a geometric transition in toric geometry. The T-dual type IIA picture and M-theory lifting are also considered.
