摘要:

分子标记技术是继形态、细胞和生化标记之后发展起来的一项重要的遗传标记手段,在解析小麦性状的分子遗传基础方面发挥着至关重要的作用。本研究系统梳理了近年来国外在小麦产量、品质及抗病性相关性状分子标记方面的研究进展,归纳了与千粒重、粒型和小穗数等产量性状,蛋白质含量、面筋含量和微量元素等品质性状,以及叶锈病、条锈病和赤霉病等抗病性状相关的分子标记定位成果,总结了已鉴定的关键基因/QTL、相应标记类型及其应用现状。在此基础上,分析了当前研究中存在的遗传群体遗传变异不足、遗传图谱精密度有限和微效位点难以鉴定等问题。提出应加强科研单位间有效合作,构建精密遗传图谱,准确评估群体结构和亲缘关系,开展多年多点表型鉴定,并在挖掘主效位点的同时,兼顾对微效位点的研究。本综述旨在为中国小麦的标记辅助育种提供理论参考和技术支撑。

Abstract:

Molecular marker technology is an important genetic marker method developed after morphological, cellular and biochemical markers, which plays an important role in analyzing the molecular genetic basis of wheat traits. To systematically review international progress in this area, this paper summarizes recent findings on the mapping of molecular markers linked to yield components (thousand-grain weight, grain shape, spikelet number), quality traits (protein content, gluten content, micronutrients), and disease resistance traits (leaf rust, stripe rust, Fusarium head blight). It also outlines the key genes or QTLs identified, the types of markers used, and their current applications. Based on this, the paper analyzes several challenges in current research, including limited genetic variation within mapping populations, insufficient precision of genetic maps, and difficulties in detecting minor-effect loci. To address these issues, we propose enhancing collaboration among research institutions, constructing high-density genetic maps, accurately assessing population structure and relatedness, conducting multi-year and multi-location phenotyping, and focusing on both major and minor-effect QTLs. This review aims to provide a theoretical foundation and technical support for marker-assisted breeding of wheat in China.
