      abstract = {Late maturing α-amylase (LMA) is a genetic defect in some  wheat lines that when triggered by particular environmental  conditions damages the grains’ starch and reduces its  suitability in processing. To lessen the risk of LMA  expression in Australia’s wheat crops, a testing regime is  now part of the nation’s varietal classification system.  This paper analyses the impact of relaxing the testing  regime and thereby providing farmers with the option to  grow higher yielding varieties with higher risks of  expressing an LMA defect that causes a price downgrade. We  model the potential for quality downgrade by incorporating  an expected price into the wheat supply and demand  functions. The expected price is generated using the price  differential between milling and feed grades and the  probability of LMA exhibition. The net benefit from  shifting between the current and more relaxed testing  regimes is evaluated as the change in producer surplus. The  analysis is based on the Western Australian wheat industry  that supplies around half of Australia’s wheat exports.  Initial findings indicate that the expected net benefit to  the wheat industry in Western Australia from a relaxation  of the current LMA policy is around $18m per annum.},
