This study summarizes the rapeseed yield-related genes identified through QTL mapping and genome-wide association study, introduces the roles of several major hormones, and also analyzes the key pathways and regulatory networks of the proteome and metabolome in photosynthesis, lipid accumulation, energy metabolism, and stress response. The results indicated that auxin, cytokinin and gibberellin all played significant roles in branching, grain size and seed development. The synthesis, transportation and source-reservoir relationship of carbohydrates play a decisive role in the formation of yield. Epigenetic modifications can affect gene expression and the adaptability of plants to the environment. Environmental factors such as temperature, light and moisture can also affect the stability of yield through hormones and signal transduction pathways. This study aims to establish a systematic regulatory model for the formation of rapeseed yield, providing theoretical references for future molecular breeding of high-yield, stress-resistant and high-quality varieties.
