油菜隐性细胞核雄性不育的研究进展

油菜细胞核雄性不育是油菜杂种优势利用的重要途径。近年来,油菜隐性细胞核雄性不育研究取得了一些进展并育成了一批核不育杂交种。为了促进核不育研究的深入及油菜杂种优势利用水平,对双隐性核不育和隐性上位互作核不育2种类型的核不育系统的遗传模式、相关基因定位以及其不育分子机理方面的研究进行综述,并对其研究成果在将来油菜杂交育种中的利用进行展望。

Research Progress on Recessive Genic Male Sterility of Rapeseed

Recessive genic male sterility is an important way of heterosis utilization in Brassica napus. In recent years, significant progress has been made in research on genic male sterility, and a batch of genic sterility hybrid varieties has been developed using this system. To understand genic male sterility further and enhance the utilization of heterosis in Brassica napus, this paper summarized the progress of two types of genic male sterility on their genetic basis, gene mapping of related genes, and molecular mechanism of sterility. Meanwhile, prospective of this knowledge for heterosis utilization was discussed.
