The following theorem is proved. Theorem: Let G be solvable with \(O_ p(G)=\{1\}\) and \(p^ 2\) does not divide \(\beta\) (1) for all irreducible Brauer p-characters of G. Then: a) G has elementary abelian Sylow p- subgroups. b) \(p^ 2\) does not divide \(\chi\) (1) for all complex irreducible characters \(\chi\) of G. The proof of the theorem has been established by means of Clifford theory and theory of the Fitting subgroup of a finite group.
