Abstract: The twisted reduced model of large N QCD with two adjoint Wilson fermions is constructed applying the symmetric twist boundary conditions with flux k. This is the one-site model, whose large N limit (large volume limit) is expected to be conformal or nearly conformal. The string tension calculated at N=289 approaches zero as we decrease quark mass in the way consistent with the theory governed by an infrared fixed point. We also discuss the twisted reduced model with single adjoint Wilson fermion. The string tension remains finite as the quark mass decreases to zero, supporting that this is the confining theory.
