摘　　要：Both Brassica juncea（mustard）and B.napus（rapeseed）are allotetraploid species of Brassica.Although these two species have their unique characters,they possess a common A genome and a few homeologous chromosomes between the genomes B and C,which provide the foundation for transfer of superior traits from B.juncea into worldwide cultivated B.napus.The unique characters of B.juncea were summarized,breeding procedure for introgression of superior traits from B.juncea into B.napus by the interspecific crossing proposed,and some recently developed rapeseed germplasm lines with novel traits such as yellow seed and super oil content,restorer of fertility for pol CMS,extreme early maturity,high oleic acid content and short-staure plant briefly introduced in this paper.分析了芥菜型油菜独具的优良性状,提出了通过种间杂交将芥菜型油菜优良基因导入甘蓝型油菜的基本程序,并对所获得的甘蓝型油菜黄籽超高油分、细胞质雄性不育恢复系、极早熟、高油酸和矮杆抗倒等新种质进行了介绍。
