Ancient Grain, Modern Innovation: How Gene Editing Strengthens Ethiopia’s Teff Harvest

SUMMARY: Teff is a vital crop in Ethiopia, providing up to two-thirds of the country’s protein and dietary fiber. Though central to Ethiopian identity, nutrition, and rural livelihoods, teff cultivation remains labor-intensive and vulnerable to agronomic challenges like lodging, which reduces yields and marketability. Corteva, in collaboration with the Ethiopian Institute of Agricultural Research and the Donald Danforth Plant Science Center, applied gene-editing technologies to develop shorter and sturdier teff varieties that can stand up to strong winds. This innovation, now supported by the Bill & Melinda Gates Foundation, aims to reduce lodging-related yield losses by up to 25%, ease labor demands, and enhance both productivity and nutritional composition. Accelerating this innovation to smallholder farmers will help improve the production of a crop which is key to feeding the world.

Teff is a vital staple crop in Ethiopia- nutritionally dense, culturally significant, and economically vital for millions of smallholder farmers. Deeply rooted in Ethiopian identity and cuisine, teff contributes as much as two-thirds of daily protein intake Ethiopian households. It is naturally gluten-free and rich in iron, calcium, fiber, and essential amino acids like lysine, making it increasingly attractive in global markets.

Among cereal grains cultivated by Ethiopian smallholders, teff commands the highest market value. Despite these benefits, teff remains one of the country’s least productive cereal grains, with average yields of just 1.76 tons per hectare. Its tall and thin stalks are highly susceptible to lodging, which reduces yields, compromises grain quality and safety, and limits market potential, ultimately threatening farmer incomes.

Corteva, in collaboration with the Donald Danforth Plant Science Center’s Institute for International Crop Improvement (IICI) and the Ethiopian Institute of Agricultural Research, has advanced teff productivity through innovation. By combining gene-edited technologies with conventional breeding, the collaboration developed short-stature teff varieties that better withstand lodging. Now supported by the Bill & Melinda Gates Foundation, this work aims to reduce lodging-related yield losses by up to 25%, improve nutritional composition, and ease labor demands- directly supporting the smallholder farmers who depend on this culturally significant and nutritionally dense crop.

Accounting for 20-25% of Ethiopia’s national grain production, teff is an ideal crop due to its long shelf-life and resilience to both drought and waterlogging. However, low productivity- exacerbated by climatic variations and labor-intensive cultivation- continues to hamper production. Strategic, science-driven collaborations accelerate innovation and offer a pathway to agricultural transformation. By improving yields, supporting farmer resilience, and preserving the cultural heritage of teff, these innovations contribute to food and nutrition security across Ethiopia, demonstrating the power of collaborative research to drive productivity growth.
