" Biochemical and genetic solutions to grain defects elimination and grain quality improvement.. The grain biochemistry program at the University of Adelaide incorporates research projects on preharvest sprouting, late maturity a-amylase (LMA), black point, colour and colour stability of Asian noodles, and durum germplasm suited to production in the southern region... Biochemistry and genetics are used to establish a better understanding of the mechanisms involved in particular traits, which then provides a base for developing better screening technologies, accurate phenotyping required for molecular marker discovery, identifying genetic variation and producing improved and novel.....

Catalogue: GRDC Final Reports
The project has provided new information on noodle colour and colour stability and in particular germplasm and screening technologies required by wheat breeders to significantly reduce polyphenol oxidase (PPO), a significant component of noodle darkening... Substantial progress has been made towards optimising levels or activities of some components, e.g. PPO, xanthophyll and lipoxygenase, whilst further research is required to realise potential improvements in other components... The procedure is technically demanding but will provide an accurate measure of apigenin content that is required for germplasm surveys and QTL location...
