The procedures to be followed and some of the problems which arise in defining breeding objectives are discussed. Special emphasis is given to attempts to reconcile con flicts between differen t bases of evaluation, and it is concluded that from a long-term viewpoint, efficien cy should be the goal of the breeder, where efficien cy is measured as the ratio of the value of a ll inputs to the value of a ll outputs. In the shorter term, or where a r tific ia l distortions of markets occur, other objectives may be preferred. Goals should be clearly distinguished from selection criteria , and this w ill be more lik ely to be achieved i f careful attention is given to the level of analysis which is employed.
