Using Ward identities of N = 1/2 supersymmetric Yang-Mills theory, we show that while antichiral gluino condensates remain invariant under the C deformation, chiral gluino correlators can get contributions from all gauge fields with instanton numbers k ≤ 1. In particular, a Ward identity of the U(1)_R symmetry allows us to determine the explicit dependence of chiral gluino correlators on the deformation parameter C.
