Abstract
Rice is a staple crop critical to global food security, and panicle development directly determines yield, stress tolerance, and quality. Advances in genomics and high-throughput phenotyping have greatly clarified the regulatory mechanisms of rice panicle development, with multiple key regulatory and blastresistance genes identified. Synergistic effects of nitrogen and planting density, as well as high-throughput panicle phenotyping using drones and YOLOv8, have also been established. However, polygenic and gene– environment interactions remain poorly understood. Further research on synergistic regulation and technical optimization is urgently needed to accelerate breeding of high-yield, high-quality, and stress-tolerant rice varieties.
