Abstract
This study analyzes changes in wheat grain yield and nutritional quality from 1850 to 2016 using samples from the Broadbalk Continuous Wheat Experiment and herbaria worldwide. Results indicate an increase in carbohydrate content but a decrease in mineral composition and protein content, particularly after the 1960s, coinciding with rising CO2, temperature, and shorter straw varieties. The implications of altered crop physiology are discussed.
