Suppose that the structure vector field ξ of M is an eigen vector field of the Ricci tensor S, Sξ=βξ, β being a function. We study on M, a gradient pseudo-Ricci soliton as an extended concept of Ricci soliton, closely related to pseudo-Einstein real hypersurfaces. We show that a 3-dimensional ruled real hypersurface of M²(c), c<0 admits a non-trivial gradient pseudo-Ricci soliton.Ricci solitonsSphere theorems
