Targeted breeding for drought-prone environments.
Targeted breeding for drought-prone environments achieves improved genetic gain through enhanced MET-TPE alignment, with a significant impact on on-farm crop productivity.
- Why it matters: Addressing drought-related yield loss is critical as current breeding methods often fail to predict performance in diverse, high-frequency drought conditions within actual farming environments.
- What they did: The study applied the extended Breeder's Equation, incorporating trait genetic correlations, and used Multi-Environment Trials combined with enviromics and phenomics to characterize drought environment types across 50 environments.
- The result: Enhanced MET-TPE alignment improved the transfer of genetic gains to farms, while poor alignment led to prediction failure despite high within-MET accuracy, emphasizing the importance of environment-specific breeding strategies.
