简介
    Core Ideas
  • UAS captured increased genetic variation compared with manual terminal height.
  • There were small significant differences in ground filtering methods to extract plant structure.
  • Higher resolution did not improve imagery informativeness with regard to plant height.
  • Logistic function provides informative phenotypes for temporal maize growth.
  • Correlation and prediction accuracy of grain yield increased by ∼20% with UAS heights.
Weekly unmanned aerial system (UAS) imagery was collected over the College Station, TX, 2017 Genomes to Fields (G2F) hybrid trial, across three environmental stress treatments, using two UAS platforms. The high‐altitude (120‐m) fixed‐wing platform increased the fraction of variation attributed to genetics and had highly repeatable (R > 60%) height estimates, increasing the genetic variance explained (10–40%) over traditional terminal plant height measurement (PHTTRML …
