摘要:

双单倍体(DH)技术能快速实现基因型纯合、缩短选育周期、提高育种效率,该技术在玉米育种中应用广泛。然而,DH技术在水稻品种选育中的研究与报道尚显不足。本文系统梳理了DH技术在水稻中的研究进展,详细阐述了单倍体诱导、染色体加倍、筛选与鉴定的关键流程,分析了其在基础研究中的多元化应用,包括构建遗传图谱、定位数量性状位点(QTLs)、在单倍体阶段进行基因编辑以快速创制纯合突变体,以及在基因组测序等前沿领域的探索。此外,还总结了DH技术在水稻新品种培育中的应用情况。针对当前单倍体技术在水稻育种过程中面临的植株矮小、存活率低、诱导效率不稳定等问题,本文提出了优化该技术的策略,例如通过利用多样化的种质资源进行杂交,在单倍体阶段进行基因编辑,以及整合分子标记辅助选择、全基因组选择或多基因协同编辑等方法。最后,本文对未来水稻DH育种的发展方向进行了前瞻性展望,以期为此项技术在水稻新品种培育中的应用提供理论参考。

Abstract:

Doubled Haploid (DH) technology can rapidly achieve genotypic homozygosity., shorten the breeding cycle, and enhance breeding efficiency. It has been widely applied in maize breeding. However, reports on its application in rice variety selection remain relatively limited. This paper reviews the research progress of DH technology in rice, summarizing the processes of haploid induction, chromosome doubling, screening, and identification. It analyzes the applications of this technology in fundamental research areas such as constructing genetic maps, mapping quantitative trait loci (QTLs), editing haploid genes, creating homozygous mutants, and genome sequencing. Additionally, it summarizes the application of DH technology in the development of new rice varieties. To address challenges like plant dwarfism, low survival rates, and unstable induction efficiency encountered during rice breeding using haploid technology, strategies are proposed to optimize the technology, including utilizing diverse germplasm resources for hybridization, gene editing at the haploid stage, and integrating molecular marker-assisted selection, genomic selection, or multi-gene synergistic editing. Finally, this review provides insights into the future development directions of DH breeding in rice, offering a theoretical reference for its application in cultivating new rice varieties.
