The selection goal or breeding objective is the starting point for any selection program. Yet as indicated by Brascamp (1978), defining the breeding objective has received the least attention of any of the stages of optimizing breeding schemes. When the breeding objective is a single trait, it is complete when the trait to be improved is chosen. The inclusion of multiple traits in the selection objective requires some form of relative weighting of the traits. Net returns or profit provide a reasonable basis for determining these relative weights for many producers.
