分子标记技术在辣椒研究中的应用进展

分子标记是生物学研究的一个重要工具，在作物新品种选育等方面发挥着越来越重要的作用。为了构建辣椒分子标记辅助育种技术体系，以实现常规育种技术与现代生物技术的有机结合，归纳了分子标记技术在辣椒种质遗传多样性、分子连锁图谱构建、分子标记辅助选择育种和基因定位等方面的已有研究成果；认为分子标记技术在辣椒上的应用研究系统性还不强、基础分子信息比较缺乏、遗传图谱还不精细，建议在实用新型分子标记开发、核心种质分子信息库建立、优良作图群体及精细遗传图谱构建等方面加强系统深入的研究。

Progress of Molecular Marker Technology in the Application of Pepper Research

As an important tool for biological research, molecular markers played an important role in crop conventional breeding. In order to construct pepper marker- assisted selection system for achieving a combination of conventional breeding and modern biological techniques, great progress in pepper genetic diversity, genetic linkage map construction, marker-assisted selection and gene clone had been summarized. It showed that molecular marker used in pepper research was not well studied, basic information limitation and genetic linkage map rough. Many studies must be strengthened in new molecular maker developing, core cultivar bio-information bank construction and refined genetic linkage map construction.
