| 摘 要： | 利用大白菜的显性核不育基因向白菜型油菜上转育，成功地育成了白菜型油菜３种不育系。其配合力测定的总趋势：甲型不育＞全不育＞乙型不育。经遗传分析、选育，找到了上位显性核互作恢复基因（Ｍｓ），它对核不育基因（Ｓｐ）具有上位恢复作用。育性是由２对显性核不育基因（Ｓｐ－）和上位显性核互作恢复基因（Ｍｓ－）控制的。并弄清了其相应遗传模式。

| Abstract: | Making use of the transforming dominant interactive gene of GMS from Brassica pekinensis to B. campestris, three sterile lines have been successfully breeded. The general tendency of the test of combining ability is as follows: homozygous sterile >fully sterile >heterozygous sterile. A restoring gene with epistaic dominant nucleus interaction character has been obtained through genetic analysis. Fertility is made of dipdysgenesis dominant interaction of GMS gene (Sp -) and epistatic dominant nucleus interaction of restoring gene (Ms -) of control. And the relative genetic model is made clear. |
