Episode notes
Measure Retention Curves Under Stress
- Track flower and pod counts over time to identify climate-resilient varieties.
- Use retention curves under stress to pick genotypes that preserve reproductive structures.
Phones Approach Manual Accuracy
- Smartphone image-based phenotyping can achieve heritability near hand-count accuracy.
- That raises signal and reduces noise, improving selection decisions at scale.
Swap Clipboards For Quick Imaging
- Use smartphone imaging to collect entire plots in under 30 seconds.
- Replace slow manual scoring to gain orders-of-magnitude efficiency and better accuracy.
