分子标记在葡萄遗传育种研究中的应用

Application of Molecular Markers on Grapevine Genetics and Breeding

分子标记是随着分子生物学技术的发展出现的一类重要的遗传标记,近年来发展迅速。分子标记技术是研究葡萄起源和新品种选育的重要工具,目前已在葡萄遗传育种等方面的研究中得到广泛应用。该文综述了近年来分子标记在葡萄种质资源鉴定、分子遗传图谱构建以及分子标记辅助育种等方面的应用,评述了分子标记在葡萄遗传育种等方面的应用前景以及目前存在的问题,以期为优质葡萄种质资源的挖掘和分子标记辅助育种提供一定的理论依据。

Molecular marker has been widely used on various aspects of grapevine breeding, which is one of important genetic markers developed from molecular biology. Molecular markers facilitated the research on investigation the origin of existed grapevine cultivars and provided a powerful tool for creating of new grapevine cultivars. The application of molecular markers, genetic mapping and molecular marker-assisted breeding in grapevine germplasm in recent years were summarized and the application prospects of molecular markers in grapevine breeding were evaluated in this paper. What s more, the existed problems in grapevine breeding were pointed out to provide foundations for molecular markers application in germlpasm resource research and marker-assisted breeding grapevine.
