Abstract Global climate change has driven breeding programs to develop abiotic stress‐resilient plant varieties. Traditionally, assessing drought resilience involves labor‐intensive and time‐consuming processes. This study used an unmanned aerial system (UAS) predict key phenotyping traits in maize ( Zea mays L.) monitor response during the crop cycle. We grew transgenic hybrids two trials, one irrigated another subjected stress, a drone equipped with red–green–blue (RGB) multispectral sensors capture images of plots over time. Machine learning models various prediction scenarios revealed significant correlations between vegetation indices Interestingly, RGB sensor outperformed trait prediction. Prediction accuracy across untested genotypes environments ranged from 0.40 0.70 for grain yield, 0.43 0.69 days anthesis, 0.51 0.67 silking, 0.35 0.57 height. Ridge random forest consistently delivered most accurate predictions environments. The normalized green–red difference index, VARI, RCC also effectively predicted captured drought. highlights value UAS as practical tool stress due its straightforward implementation.
