What it is
Transgenic wheat carrying a sunflower gene (HaHB4) that improves yield under drought. Argentina approved it in 2020 as the world's first transgenic wheat for commercial cultivation.
Approval for cultivation in Argentina in 2020; the gene was isolated from research at the National University of the Littoral begun in the 1990s. Real-world yield is debated among trials.
What it led to
- Drought-tolerant crops
- Approvals in Brazil and the United States
- Regulatory debate on transgenic wheat
