Abstract: A high-density molecular linkage map will be of value for studies designed to assay genetic variation,identify markers associated with dissect quantitative trait loci,and perform marker-assisted selection to improve agronomically important traits within plants.By polyploid nature and high levels of heterozygosity of vast majority pasture plants,it was rather complicated to construct linkage maps of them.Naw an extensive list of linkage maps have been dvafted.The objective of this paper is to introduce the present conditions of linkage maps construction and available measures as well as contributing some suggestions for scaling quality genetic maps of forages.

Key words: Pasture, Genetic linkage maps, Qutline

摘要: 高密度分子连锁遗传图谱对分析植物遗传变异、标记目标性状、数量性状定位和分子辅助选择改良性状均具重要价值。由于大多数牧草的多倍性和高度异质特点,牧草遗传连锁图谱的构建相对复杂。目前,一定数量牧草的遗传连锁图谱已经产生。本文简要综述了牧草遗传图谱研究现状和常用策略,提出了构建高质量牧草遗传图谱的建议。
