Ex-soviets key to wheat
Has indicated the world's grain growers are likely to produce enough wheat to keep the global population fed.But the analysis is predicated on whether farmers can maintain current yield gains and there being no catastrophic disasters in major growing regions.
CSIRO crop scientist Tony Fischer said it would be difficult for wheat breeders to continue making gains at the current rate of about 1 per cent a year.
At last week's Grains Research and Development Corporation farm adviser research update in Ballarat, visiting British cropping specialist Jim Orson said wheat yields in Britain peaked at about eight tonnes a hectare in 1996 after rising steadily from about four tonnes/ha in the 1970s.
But Mr Orson said wheat yields had almost plateaued since 1996 and would continue at relatively flat rates unless new technology could be found to give the industry another burst in growth.
"That must be in plant breeding and it is probably GM (genetically modified) technology," he said.
