Why we fly: Revolutionizing wheat phenotyping with drones

By Cally Arthur/Cornell University

CIUDAD OBREGÓN, Mexico- Ravi Singh compares plots of wheat lines growing in the fields of Obregón to determine which lines have potential as new varieties. Relying on reams of statistical breeding data and an experienced eye, the head of bread wheat improvement at the International Maize and Wheat Improvement Center (CIMMYT) evaluates plants for resistance to rusts and other diseases, height, tillering ability, grain fill or the mass and size of the spikes, and general vigor or robustness. After detailed evaluation, the fate of the plant is determined: it is selected for advancement and harvested for seed for a yield trial, or it is passed over. With his team, Singh surveys tens of thousands of small wheat plots each season.
