  Let G be a p-solvable group, P a p-subgroup and chi in Irr(G) such that
chi(1)_p \ge |G:P|_p. We prove that the restriction chi_P is a sum of
characters induced from subgroups Q\le P such that chi(1)_p=|G:Q|_p. This
generalizes previous results by Giannelli--Navarro and Giannelli--Sambale on
the number of linear constituents of chi_P. Although this statement does not
hold for arbitrary groups, we conjecture a weaker version which can be seen as
an extension of Brauer--Nesbitt's theorem on characters of p-defect zero. It
also extends a conjecture of Wilde.
