摘要
甘蔗许多重要性状是质量性状或数量性状,受单基因或多基因控制,对这些性状进行基因定位对甘蔗育种研究具有重要意义。近年来随着分子生物学特别是分子标记技术的快速发展,使质量、数量性状基因定位研究可以更深入地进行,同时也促进了标记辅助选择(Marker—Assisted Selection,MAS)育种技术快速发展起来。综述了近年来国内外在分子图谱构建、甘蔗基因定位和分子辅助育种方面的研究进展,讨论了当前出现的问题及解决方法,同时展望了该领域的发展前景。
Many important traits of sugarcane are quality trait or quantity trait, which are controlled by single gene or polygene, locating these genes is very important in sugarcane breeding. In decade years, with fast development of molecular biology, special molecular marker technique, benefited in further study of locating genes and accelerated the development of MAS (Marker-Assisted Selection) technique in sugarcane breeding. These studies introduced the research works in constructing molecular marker mapping, locating gene, MAS breeding. The problems and prospect in this field are discussed.
