DNA分子标记技术在桑树上的应用研究进展

近年来,随着分子生物学及其技术的快速发展,分子标记技术已在各种作物种质资源鉴定与分类、遗传图谱构建、基因定位以及育种中广泛应用。文章介绍了几种常用分子标记技术的原理、方法、特点及其在桑树上的应用现状,指出今后应加强分子标记技术在桑树遗传图谱构建、亲缘关系和系统分类、种质资源的保存和利用、优良性状基因定位、辅助选择育种等方面的研究,缩短桑树育种进程,改良现有桑树品种,选育高产、优质、多抗桑树新品种。

Advance in DNA molecular marker applications in mulberry

In recent years,molecular marker technology has been widely applied for identification and classification of germplasm resources,construction of genetic maps,gene mapping and molecular breeding of various crops.The princi-ple,method and characteristics of several molecular markers and their application in mulberry have been discussed in the present article.It has been suggested that the application of molecular markers should be strengthened for the construction of genetic maps,identification of genetic rel...
