以甘蓝型油菜隐性胞核雄性不育系１１７Ａ同一株系原种为材料进行不育率鉴定的结果：条播不匀苗、行长为２ｍ、播种量为１．０～１．５ｇ的鉴定技术，准确率可达９５％以上，既节约用种，又准确可靠；同苗床大苗比小苗的不育率要低７．９％左右，这一结果解决了大面积两系制种的一个重要的制种技术问题，即育苗移栽时不能只栽大苗弃小苗，否则，将明显增加拔可育株的工作量和降低制种产量
The results showed that the male sterile line 117A with the same strain of the same strain of rapeseed as the male sterile line was used for the identification of the infertility rate. The uneven seedling length was 2m and the sowing rate was 1.0 ~ 1.5g Technology, the accuracy rate of up to 95%, not only save the species, but also accurate and reliable; seedlings with seedlings than the seedling sterile rate of about 7.9% lower, the result of this solution to a large area of two lines of an important Seed production technology problems, that is, seedlings can not be transplanted only big seedlings abandoned seedlings, otherwise, it will significantly increase the workload of unpolluted strains and reduce seed production
