We've been growing wheat for 10,000 years. In fact, one in five calories consumed by humans today comes from wheat.
But most ancient wheat varieties have been displaced by modern kinds, which were bred to have higher yields and feed more people.
And modern wheat is beset with problems - from diseases to the environmental impact of industrial farming.
Now, a collaboration between British and Chinese scientists is exploring how to use the genes of ancient wheat to solve modern issues.

Graphene was meant to change the world. What happened?
RAZOR visits the John Innes Centre in Norwich, home to the Watkins collection, a repository of ancient wheat grains that was established by pioneering botanist Arthur E Watkins a century ago.
Lead researcher Dr. Simon Griffiths explains how researchers have found traits like salt resistance and slug resistance in the genes of ancient wheat.
We also speak to Professor Shifeng Cheng, a senior scientist at the Agricultural Genomics Institute in Shenzhen, whose team sequenced the DNA of all 827 remaining bread wheat varieties in the Watkins collection.
Professor Paul Nicholson from the John Innes Centre explains how that genetic sequencing work is helping scientists in the UK work out which ancient genes can be used to treat crop-destroying diseases, like wheat blast and fusarium head blight.
