研究以秦油2号出现的不育株（简称陕ZA）为基本材料，与自育和引进的国内外单双低（低芥酸、低硫么）油菜品种（系）为父本．采用刚交、回交的方法育成了一批单双低甘蓝型油菜胞质雄性不育系及其相应的保持系，并实现了“三系”配套。在不育系的选育中发现，无论是单低或是双低不育系，其不育性的差异主要表现在不育度上，一些表现彻底不育．一些表现有微粉、这主要决定于保持系；且在这些不同的不育系之间，不同的目交方式之间所得到的自交亲和指数不同。同时还进行了新的单双低恢复系的选育研究，已取得了初步进展。
In this study, sterile line Qin A 2 (Shaan ZA) was taken as the basic material, and self-bred and introduced single-and double-low (low erucic acid, low sulfur) rape varieties (lines) as the male parent. A series of CMS lines and their corresponding maintainer lines were bred using the methods of freshly cross and backcross, and a “three lines” package was established. In the selection of CMS, we found that the difference of sterility, whether single low or double low CMS, mainly showed in sterility, and some showed complete infertility. Some of the performance of the powder, which is mainly determined by the maintainer; and in these different male sterile lines, different methods of intercourse obtained self-compatibility index is different. At the same time, the research on the breeding of new single and double low restorer lines has been carried out and some preliminary progress has been made.
