摘要
本文对核不育系分离出的各比例的可育株进行了较大群体的自交套袋观察，结果发现：在兄妹交可育株自交后代以及不育株与常规品种杂交的Ｆ２代可育株自交后代中出现了育性分离，其分离比大部分符合１５∶１，其中也存在１３∶１的分离群体。通过对可育株自交后代育性表现的遗传分析，再次证明了我们目前研究的显性核不育亚麻是个复杂的群体。
Investigation on selfcrossed offspring covered packet was carried out in fertile plants separated from sterile line. The results showed that fertility separation occurred in selfcrossed offspring of fertile plants and the separation rates were about 13∶3 and 16∶1. So this conclusion testified again that dominant nucleus sterile flax studied is a complex population.
