Scientists crack genetic code of wheat in search of higher yields
Friday, August 27, 2010

The team hopes that the breakthrough - which saw scientists mapping a code five times larger than that of humans - will relieve pressure on the world's wheat supply.

The annual wheat harvest is more than 550million tonnes worldwide, and is worth £2billion to Britain's agricultural industry.

Professor Keith Edwards, one of the researchers from the University of Bristol, said that the project had been a 'huge challenge for scientists.'

Scientists have not yet produced a finished copy of the code, though the blueprint should give them access to roughly 95% of the world's wheat crops.

Dr Anthony Hall, a member of the team from the University of Liverpool, said: 'Wheat production is already under pressure with failures in the Russian harvest driving up world wheat prices. It is predicted that within the next 40 years world food production will need to be increased by 50 per cent.

'Developing new, low input, high-yielding varieties of wheat will be fundamental to meeting these goals. using this new DNA data we will identify variation in gene networks involved in important agricultural traits such as disease resistance, drought tolerance and yield.'

The project was funded by the Biotechnology and Biological Sciences Research Council.
