Global food security is a major challenge in the 21st century, exacerbated by increasing frequency and intensity of extreme climatic events under climate change. The extreme climatic events around flowering, such as intense heatwaves and droughts, threaten crop yields by impacting reproductive development and grain setting. Our study estimated the potential impacts of short-term, high impact extreme temperature and drought eve...

The use of plant genetic resources (PGR)—wild relatives, landraces, and isolated breeding gene pools—has had substantial impacts on wheat breeding for resistance to biotic and abiotic stresses, while increasing nutritional value, end‐use quality, and grain yield. In the Global South, post‐Green Revolution genetic yield gains are generally achieved with minimal additional inputs. As a result, production has increased, and milli...
