The world could theoretically double the amount of wheat it produces by breeding versions of the crop that are genetically optimised for different regions. However, crop scientists not involved in the work are sceptical.

Crop experts have previously estimated the “management gap” – or the difference between existing yields of wheat and the theoretical potential yield that could be achieved with better management of irrigation, fertiliser and other factors. Now, for the first time, a …
