The planting of a new experimental crop of genetically modified (GM) wheat will take place this spring after the UK government gave the final go ahead.
The GM wheat has been engineered to use sunlight more efficiently and has boosted greenhouse yields by up to 40%.

Researchers in Hertfordshire now want to see if they can replicate these gains in the field…
This latest effort aims to see if the spectacular gains in productivity of 20-40% in GM wheat grown in the greenhouse can be reproduced in the open air.
Last Autumn, the scientists at Rothamsted Research submitted an application to the Department of the Environment, Food and Rural Affairs (Defra) seeking permission to carry out small field trials at a secure site near Harpenden between 2017 and 2019.
After an independent risk assessment and a public consultation, that permission has now been granted.
