DNA分子标记技术及其在高粱育种中的应用

近年来分子技术的快速发展，使其在高粱上也得到应用。由于分子标记具有诸多优点，因此它的发展和应用为高粱研究提供了一条有效的途径。此文概述了分子标记技术的基本类型，综述了近年来分子标记技术在高粱遗传连锁图谱的构建、基因定位、关联遗传学、突变体等的研究及应用现状。最后，分析了分子标记技术在高粱遗传育种研究中存在的问题及今后发展的方向。

A Review of DNA Molecular Markers and Its Application in Sorghum Breeding

In the recent years, the molecular techniques developed rapidly, and it was used in Sorghum diversity. DNA mo1ecular markers had many advantages compared with the traditional methods, so they were efficient techniques in Sorghum research. This paper briefly introduced six major types of DNA molecular markers, and summarized the present situations of molecular markers in relevant study and application in sorghum breeding in past years, such as the construction of genetic spectrum and gene locating, associati...
