Results

• Higher yielding varieties have lower reflectance values in the VIS and red-edge spectra portions and higher values in the NIR portion of the spectra and lower canopy temperatures than lower yielding varieties.
• Canopy temperature and canopy reflectance measurements can account for a large portion of variability in seed yield among varieties.
• Attempting to build upon these results to develop applications in high throughput phenotyping.
