Global Wheat Health Alliance Launched to Strengthen Disease Resistance in Wheat

Efforts to protect wheat from fast-evolving diseases in South Asia and East Africa are getting a new international push through the Global Wheat Health Alliance (GWHA), a partnership within the Disease-Resistant Wheat Hybrids Initiative, known as HyBread. Co-led by CIMMYT and Cornell University, GWHA will connect gene discovery, field testing and pre-emptive breeding to help deliver stronger disease resistance in new wheat varieties and hybrids.

Wheat is the world’s second most widely cultivated crop, grown on more than 220 million hectares and serving as a staple food for billions of people. About one quarter of the world’s wheat-growing area is in South Asia and East Africa, where roughly 170 million tons are produced each year. In these regions, rapidly evolving fungal diseases including stem rust, yellow rust, wheat blast, and Fusarium head blight are threatening improved varieties and breeding populations, placing decades of agricultural progress at risk.

GWHA is designed to move resistance more efficiently from research into breeding pipelines and, ultimately, into farmers’ fields. Field testing sites in Kenya, Mexico, Bolivia, Bangladesh, and Ethiopia will evaluate thousands of wheat lines under high disease pressure, while research partners contribute resistance genes, gene-editing mutants and molecular markers that can accelerate selection.

Over three years, the alliance will generate large-scale disease phenotyping data, deliver wheat lines with stacked resistance to major diseases and train at least 100 scientists in disease evaluation and resistance breeding. Within HyBread, GWHA provides the foundation for stable disease resistance needed to support successful hybrid wheat development.

The partnership brings together complementary and world-leading strengths. CIMMYT leads disease screening, breeding and global germplasm distribution. The Borlaug Global Rust Initiative (BGRI), housed at Cornell University, provides scientific leadership, coordination and capacity development. The John Innes Centre and the University of Maryland contribute gene discovery, mapping, and gene editing expertise. National partners in Ethiopia (Ethiopian Institute of Agricultural Research), Kenya (Kenya Agricultural and Livestock Research Organization), Bangladesh (Bangladesh Wheat and Maize Research Institute), and Bolivia (Instituto Nacional de Innovación Agropecuaria Y Forestal) test and deploy improved materials in target environments.
