a Estimated probability of error between UAV and ground-based data sets for plots consisted dwarf and tall plants, b impact of major genes on plant height across the DH population, and c averaged plant height of Yangmai16, Zhongmai895 and DH. Error bars indicate standard deviation; lowercase letters indicate significant difference between parent cultivars; *. **, *** indicate significant differences among DH lines. B booting, DH doubled haploid lines, DTM digital terrain model, G ground, MGF mid-grain filling, PH plant height, UAV unmanned aerial vehicle
