British scientists say they have developed a new type ofwheat which could increase productivity by 30%.
TheCambridge-based National Institute of Agricultural Botany has combinedan ancient ancestor of wheat with a modern variety to produce a new strain.
In earlytrials, the resulting crop seemed bigger and stronger than the current modernwheat varieties.
It will take atleast five years of tests and regulatory approval before it is harvested byfarmers.
Some farmers,however, are urging new initiatives between the food industry, scientists andgovernment.
They believethe regulatory process needs to be speeded up to ensure that the global foodsecurity demands of the next few decades can be met, says the BBC’s Tom Heap.
One in five ofall the calories consumed round the world come from wheat.
But despitesteady improvement in the late 20th century, the last 15 years have seen littlegrowth in the average wheat harvest from each acre in Britain.
Just lastmonth, cereal maker Weetabix announced thatit would have to scale back production of some of its products due to a poorwheat harvest in the UK.资料来源：http://www.innovationtoronto.com/2013/05/cambridge-based-scientists-develop-superwheat/
