国内外研究指出,甘兰型油菜的杂交优势较强,选育优良杂交种用于生产,将大幅度提高单位面积产量。为了加速研究进程,现就我们观察所及,就不育类型的划分,胞核不育型育型遗传规律,胞核不育“两用系”的选育,自交结实性、生产力与配合力的关系,以及恢复力的调查方法等问题,加以讨论,以期收到抛砖引玉的效果。 Domestic and foreign studies have pointed out that the type of Brassica napus heterosis is strong, breeding excellent hybrids for production, will significantly improve the yield per unit area. In order to speed up the research process, we have observed, as far as we can observe, the classification of the types of infertility, the genetic law of the cytoplasm male sterile type, the breeding of the dual-purpose line of nuclear sterility, the self-fertility, productivity and cooperation Power relations, and resilience of the survey methods and other issues to be discussed in order to receive the effect of throwing one’s share of wisdom.
