亚麻分子标记应用研究进展

The Progress of Molecular Marker Applied to Flax (Linumus itatissimum )

分子标记是继形态学标记、细胞学标记和生化标记之后迅速发展起来的一种新标记。分子标记技术应用于亚麻的研究,对亚麻亲缘关系与遗传多样性、及遗传图谱构建及资源保护利用等提供了极大的便利。主要叙述了亚麻遗传多态性及亲缘关系、系普分析、种质鉴定、基因定位、遗传图谱构建和分子标记辅助选择育种等的研究进展,探讨了分子标记在亚麻研究中尚需解决的问题。

Molecular marker is a new type of genetic marker, which developed after morphological marker,cytological marker and biochemical marker. Molecular marker have extensively applied to flax＇s study during the past decade, and provided huge conveniences for the studies of genetic relationship, genetic diversity, genetic map construction and resource conservation and utilization. This paper primary illustrated the follow aspects： the genetic diversity and genetic relationship of flax, pedigree analysis, germplasm identification, gene localization, genetic map construction, molecular marker-assisted selection, and the problems of molecular marker in application of flax.
