      abstract = {The major purpose of any testing program is to establish  repeatable differences between
cultivars in a given  environment but cultivars rarely perform consistently  across the range of
environments in which they are tested.  Plant breeders recognise that the nature of  genetic
material and the environments in which it is tested  are such that there is a lot of uncertainty
involved in the  selection of superior varieties.
Economists have not been  closely involved with the cultivar selection process and  only
recently has there been much interest taken by  economists in the costs and management of
breeding programs  (Brennan et al. 1998).
This paper tries to estimate long  term variable costs of conducting regional variety trials  and
to determine the optimal number of trials for south  Queensland and northern New South
Wales graingrowing  regions.},
