If is a saturated formation of groups, we define a canonical subset of the irreducible complex characters of a finite solvable group . If is an -projector of , we show that , where is the derived subgroup of . In particular, if is the class of -groups, this reproves the solvable case of the celebrated McKay conjecture.
