The history of wheat genetic diversity

By 31st May 2019 June 11th, 2019 No Comments

Researchers have taken a detailed look at more than 4000 samples of wheat from around the world and have found how the plant has undergone a complex history of diversification and adaptation since its domestication 8,000 to 10,000 years ago. The findings, from François Balfourier of INRA and colleagues, could point to potential reservoirs of genetic diversity for new breeding programs for wheat, which is one of the most grown crops (it is estimated to provide about 15% of global calorie consumption per day). The work is published in Science Advances.
