近等基因系只有一两个基因差异,可以减少很多不必要的工作,因此在作物育种、分子标记和基因定位等方面研究有着广泛的应用。综述了甘蓝型油菜近等基因系材料的构建及近等基因系材料在抗逆、分子标记和蛋白质组学等研究中的应用情况。认为随着构建技术的推广,新型近等基因系材料将会发挥更大的作用。
Near isogenic lines have only one or two genetic differences, can reduce a lot of unnecessary work, so in crop breeding, molecular markers and gene mapping has a wide range of applications. The construction of nearly isogenic lines in Brassica napus and the application of near isogenic lines in stress resistance, molecular markers and proteomics were reviewed. It is believed that with the popularization of the construction technology, the new near-isogenic material will play a greater role.
