小麦庞大的基因组使得分子标记技术在小麦中的应用落后于大麦、玉米、水稻等作物。近年来 ,随着分子标记技术及检测系统的发展和完善 ,分子标记技术在小麦中的应用已有了很大的进展。分子标记技术依靠提供准确、稳定可靠的 DNA水平的遗传标记 ,在小麦遗传育种研究中已用于构建遗传图谱、标定和定位目的基因、鉴定与标记外源染色体片段、鉴定品种真实性和纯度、绘制品种指纹图谱、遗传分析、物种演变、标记辅助选育等方面
The huge genome of wheat makes the application of molecular marker technology in wheat lags behind crops such as barley, corn and rice. In recent years, with the development and improvement of molecular marker technology and detection system, the application of molecular marker technology in wheat has made great progress. Molecular marker technology relies on genetic markers that provide accurate, stable and reliable DNA levels and has been used in genetic breeding of wheat to construct genetic maps, identify and target genes, identify and label exogenous chromosome segments, identify authenticity and purity of cultivars, Draw variety fingerprinting, genetic analysis, species evolution, marker-assisted breeding and so on
