摘要

Sugar beet (Beta vulgaris L.), as a globally significant sugar crop, has seen substantial advancements in marker-assisted selection (MAS) research, which plays a pivotal role in enhancing breeding efficiency and quality traits. Molecular marker technologies enable precise identification and tracking of target genes associated with key agronomic traits, including disease resistance, drought tolerance, and high yield, by analyzing tightly linked molecular markers to facilitate accurate genotype discrimination in hybrid progenies for assisted selection. This paper systematically reviews the research progress of MAS in sugar beet breeding, summarizing commonly used molecular marker techniques and their applications in genetic studies of sugar beet. It highlights the development and utilization of molecular markers for key traits such as yield, quality, stress resistance, and disease resistance, while discussing the practical advances of MAS in germplasm innovation, early-stage selection, and heterosis exploitation. Research demonstrates that molecular marker technology has become a pivotal tool for precision breeding in sugar beet, though challenges remain in marker utility, multi-omics integration, and technology dissemination. This review provides theoretical insights for refining the molecular breeding framework and promoting industrial applications in sugar beet.
