摘　　要：Introducing the 1S^1 chromosome of Aegilops longissima into wheat genome can significantly improve wheat grain quality and contents of iron and zinc. Therefore, the development of molecular markers specific to 1S^1 chromosome of A. longissima is of important significance for breeding high-quality wheat with high contents of iron and zinc in grains. In this study, nine molecular markers specific to 1S^1 chromosome of A. longissima were developed, including two 1S^1S specific markers,six 1S^1L specific markers and one 1S^1 specific marker which was located on both short and long arms. The practicability of these molecular markers were verified using hybrid population as materials. The results showed that hybrid population could be effectively screened and identified, which indicated that the developed 1S^1 chromosome-specific molecular markers could be used for screening and identification of hybrid population and could be used in marker-assisted breeding of high-quality wheat with high contents of Fe and Zn in grains.导入小麦的高大山羊草(Aegilops longissima)1S^1染色体可以显著提高小麦加工品质及子粒Fe和Zn元素含量。因此,1S^1染色体特异分子标记的建立对子粒Fe和Zn元素含量高的高品质小麦的选育具有重要意义。试验建立了高大山羊草1S^1染色体特异分子标记9个。其中染色体短臂标记2个,长臂标记6个,同时定位于长臂和短臂的标记1个。利用建立的分子标记对杂交群体进行检测。结果表明,建立的9个标记可以对分离群体进行有效筛选与鉴定。因此,获得的高大山羊草1S^1染色体特异分子标记可以应用于杂交群体的筛选、鉴定以及辅助选育子粒Fe和Zn元素含量高的高品质小麦。
