1. Many progenies were obtained by a Brassica oleracea-Sinapis alba monosomic alien addition line plant selfing. 将甘蓝-白芥单体异附加系自交,获得了其自交后代。
2. The vigour of two-parent progenies was likely to be similar. 双亲本子代的生活力多半是相似的。
3. The parental specific RAPD markers could be observed at a higher frequency in their progenies. 此外,发现某些甘蔗亲本种质具有特异RAPD标记带。
4. The sprouting percentage of hybrid progenies was reduced by backcrossing with the resistant parents. 用抗性亲本回交可提高其后代的抗穗发芽性。
5. A rice floral mutant with twin-ovary and dwarf plant was isolated from the progenies of the combination of C2/Mianxiang 5B. 在籼稻保持系C2与绵香5B的杂交后代中发现了一个植株显著矮化的双子房突变体。
