New low-protein wheat could slash farming costs and reduce environmental impact.
The researchers aimed to find wheat types that make good bread with less protein. They grew 40 wheat types for 3 years, using different levels of nitrogen fertilizer. They tested over 4000 grain samples for protein content and analyzed the flour quality for bread-making. They found wheat types that make good bread with lower protein content, which could help reduce the need for nitrogen fertilizer and lower costs for farmers.
