Index selection with proportionality constraints.
Tallis [1962] formulated and solved the problem of constructing a selection index whose use will produce changes in the means of genotypic values of various traits that are proportional to ultimately desired changes. Several meaningful variations of this problem are described, and their solutions are presented in a common framework.
