Abstract
Highest priority should be assigned by breeders to fruit quality, yield, and precocious bearing, combined with at least moderately high degrees of resistance to fire blight and pear psylla.
Genetically compact or dwarf tree habits should be selected which are suitable to medium and high density plantings.
Traits such as fruit quality and yield have many components, some of which are independent, and others which are correlated.
The study of the inheritance of such complexes and genetic improvement may be aided by a knowledge of the underlying physiological relationships among the components.
The use of combining ability analysis as an aid to selection of parents for breeding appear to be promising if the assumptions of the technique are recognized.
