Results from recent diallel crossbreeding experiments are used
to illustrate the range in average genetic merit for meat and wool
production available for utilisation in our present breed resources by
crossbreeding. Performance of reciprocal first crosses suggests in
addition considerable opportunity for exploitation of hybrid vigour.
Breed differences are considerably reduced when production is expressed
relative to ewe body size, although first-generation crosses remain
superior to purebreds on this basis.
