Caption

(A) Processing steps for RGB and LiDAR data. (B) Each of the 419 cotton plots was precisely demarcated. The difference between the first and 95th percentiles was used to extract the PH from the on-season digital surface model (DSM) of the plot RGB images. The PH was calculated as the difference between the DSM and digital terrain model (DTM) of the plot LiDAR data. (C) UAV-based PH was used for K-means clustering and a genome-wide association study (GWAS).
