- 摘要:
- 密植栽培是突破大豆单产瓶颈的重要途径，但其引发的群体胁迫效应（光竞争加剧、倒伏风险升高等）对品种耐密性提出更高要求。通过系统综述大豆耐密性研究进展，解析了理想耐密株型的生理生态优势，介绍了基于多性状协同的大豆综合耐密指数评价体系和耐密性关键性状关键基因定位研究进展。现有研究仍存在评价体系普适性不足、基因定位分辨率有限、多组学整合薄弱等问题。未来需融合高通量表型与人工智能技术，构建基因-环境互作动态模型，并通过分子设计育种协同优化抗逆与高产性状。
- Abstract:
- Dense planting is key to boosting soybean yield per unit area, but it presents challenges such as intensified light competition and higher lodging risks, demanding that soybean varieties possess higher tolerance to dense planting. This paper comprehensively summarized research progress on soybean tolerance to dense planting，the physiological and ecological advantages of the ideal plant type for dense planting were explained. A comprehensive evaluation system for soybean tolerance to dense planting, based on the synergistic analysis of multiple traits was presented.And research progress in the QTL mapping of key traits related to dense planting was covered. Existing research still faces problems such as insufficient universality of the evaluation system, limited gene-locus resolution, and weak integration of multi-omics. Future research should combine high-throughput phenotyping and artificial intelligence technologies to build dynamic models of gene-environment interaction and use molecular design breeding to optimize stress-tolerance and high-yield traits simultaneously.
