分子标记在蚕豆遗传育种中的研究进展

Research Progress of Molecular Markers on Genetic Breeding in Vicia faba L.

蚕豆自然异交率高造成群体内杂合度较高,通过传统的田间表型观察难以区分遗传变异,分子标记为蚕豆种质资源鉴定与聚类分析提供了新方法。本文基于分子标记类型及发展,对国内外利用分子标记在蚕豆遗传连锁图谱构建、分子辅助选择、种质资源评价和基因定位方面的研究进展进行了分析总结,并探讨了分子标记在蚕豆遗传育种中的发展前景,以期为提高蚕豆种质资源利用效率和遗传改良提供参考。

The genetic population of faba bean is relatively high heterozygosity because of its high natural outcrossing rate.It is difficult to distinguish genetic variation within a population by traditional field phenotypic traits observation.Molecular markers provides a new approach for germplasm resources identification and cluster analysis of faba bean.This article reviews the development of molecular markers and its application on genetic linkage map construction,marker-assisted selection,germplasm resources evaluation and gene mapping,as well as the prospects of the molecular markers technology in genetic breeding for faba bean.It provides a reference for the efficient utilization of germplasm resources and the genetic improvement of faba bean varieties.
