综述了分子标记的概念、特点、种类,对分子标记辅助选择技术的优势和影响因素进行了介绍,同时对其在质量性状(稻米品质、抗病、抗虫性等)改良和数量性状(稻米产量、抗逆性、株型等)改良两方面的研究进展进行了归纳,并对研究中出现的问题进行了分析,对其应用前景进行了展望。 The concept, characteristics and types of molecular markers were reviewed. The advantages and influencing factors of molecular marker-assisted selection techniques were introduced. At the same time, their effects on quality traits (rice quality, disease resistance, insect resistance, etc.) Yield, stress resistance, plant type, etc.) were summarized. The problems in the research were analyzed, and the prospect of its application was prospected.
