    Abstract
  • Flowering time is a critical agronomic trait with a profound effect on the productivity and adaptability of rapeseed (Brassica napus L.). Strategically advancing flowering time can reduce the risk of yield losses due to extreme climatic conditions and facilitate the cultivation of subsequent crops on the same land, thereby enhancing overall agricultural efficiency. In this review, we synthesize current information on flowering time regulation in rapeseed through an integrated analysis of its genetic, hormonal, and environmental dimensions, emphasizing their crosstalk and implications for yield. We consolidate multi-omics evidence from population genetics, functional genomics, and systems biology to create a haplotype-based framework that overcomes the trade-off between flowering time and yield, providing support for the precision breeding of early-maturing cultivars. The insights presented here could inform future research on flowering time regulation and guide strategies for increasing rapeseed productivity.
