Conventional sorghum breeding has long been constrained by insufficient genetic dissection of complex traits, the \u201cblack box\u201d of genotype-to-phenotype mapping, and poorly understood genotype-by-environment interactions, resulting in stagnant genetic gain. In recent years, rapid advances in multi-omics technologies\u2014including genomics, transcriptomics, epigenomics, single-cell omics, and microbiomics\u2014have propelled sorghum research from single-gene mapping to systems-level dissection of regulatory networks, providing a novel paradigm for elucidating the molecular basis of agronomic traits across all molecular layers and breaking through the bottlenecks of conventional breeding. This review systematically synthesizes recent advances in sorghum multi-omics research, dissecting the molecular basis of key agronomic traits across distinct omics layers. We summarize the integrated multi-omics precision breeding technology system and elaborate on the practical applications of multi-omics approaches for four core breeding objectives: stress tolerance, yield, quality, and nutrient use efficiency. Finally, we discuss current challenges and future perspectives, aiming to provide a theoretical framework and technical reference for molecular design breeding in sorghum.<\/jats:p>","DOI":"10.3390\/plants15192954","type":"journal-article","created":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T10:00:34Z","timestamp":1790589634000},"page":"2954","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Multi-Omics Integration Drives Precision Breeding in Sorghum: Molecular Dissection and Breeding Practice"],"prefix":"10.3390","volume":"15","author":[{"given":"Wenfang","family":"Zhou","sequence":"first","affiliation":[{"name":"School of Life Sciences, Guizhou Normal University, Guiyang 550001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyan","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Guizhou Normal University, Guiyang 550001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuntong","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Guizhou Normal University, Guiyang 550001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fei","family":"Li","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Guizhou Normal University, Guiyang 550001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"551","DOI":"10.1038\/nature07723","article-title":"The Sorghum bicolorgenome and the diversification of grasses","volume":"457","author":"Paterson","year":"2009","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"603","DOI":"10.1016\/j.molp.2019.04.001","article-title":"Sustainable agriculture: From sweet sorghum planting and ensiling to ruminant feeding","volume":"12","author":"Xie","year":"2019","journal-title":"Mol.
