摘要:
亚麻作为一种经济作物,综合利用价值高,亚麻籽丰富的营养成分和活性物质以及优质的纤维品质使得亚麻越来越受到青睐,因而培育高品质亚麻品种成为当前的育种目标。传统育种方法因周期长、选择有限等原因限制了育种进程,随着分子生物学和分子标记等技术的发展,传统育种手段结合分子育种在一定程度满足了育种需求。文章对分子标记在亚麻研究中的应用、遗传连锁图谱构建、数量性状座位定位、抗性及育性标记定位、全基因组关联分析等研究进展作一综述,并探讨亚麻分子标记辅助育种研究中存在的问题,为今后亚麻育种提供一些参考。

Abstract:
Flax (Linum usitatissimum L.) is an economic crop with multiple utilization value. The rich nutrients and active substances of flaxseed as well as high-quality fiber make flax more and more popular. Therefore, producing high-quality flax varieties has become the current breeding goal. Traditional breeding methods have the limitation of the long cycles and limited choices. With the development of molecular biology and molecular markers, the traditional breeding methods combined with molecular breeding have met the breeding requirements. This article reviews the advances made in the application of molecular markers in flax, construction of genetic linkage maps, quantitative trait loci positioning, resistance and fertility marker positioning and genome-wide association analysis. The current problems of molecular marker assisted breeding in flax are discussed to provide some references for flax breeding in the future.
