CHIPS will be free of those ugly black flecks, thanks to new Tasmanian-bred potato varieties.
Tasmanian Institute of Agriculture plant pathologist Calum Wilson has scored a major victory in a decade-long war against the potato common scab bacterial disease.
The disease causes corky scab-like lesions on tubers of the world's most important chip potato variety, russet burbank.
It forces potato processors to either reject the spuds, or to peel off large parts of them. Occasionally the unappetising discolourations make it through into the fries.
To beat the problem, Prof Wilson has gone where nobody has gone before with potatoes.
He pulverised the stems of russet burbank potato plants, breaking them down into individual cells, before using tissue-culture techniques to transform the cells into new plants.
The tissue cultures were then laced with toxins produced by the scab micro-organism.
The toxins caused most of the cultures to fail but the survivors developed into potato plants that were resistant to the scab disease.
The institute, a joint venture between the University of Tasmania and the State Government, is seeking commercial partners to put two of Prof Wilson's most promising lines into Australian supermarkets. The hope is they will eventually also make international markets. Royalties would flow to the institute.
"One of those varieties, by chance, out-yields its parent [russet burbank] by 10 to 20 per cent," Prof Wilson said.
