摘要
本文对显性核不育亚麻后代育性分离比进行卡平方测定，发现后代出现了非1：1分离现象，即侧交、兄妹交后代的分离比为1：1、5：3、3：1不育率偏高等4种类型．经反复验证，非1：1家系出现的频率为13％左右，对于这种复杂的育性分离现象，只用单基因控制的理航已无法解释。因此认为，我们目前研究的核不育亚麻是1个复杂的群体，有必要针对各不同的分离比作进一步的分析。
Existence of non-one-to-one separation was found in dominant nucleus sterile flax offspring through x2 test. The separate rates are 1: 1,5: 3,3: 1, and slightly high sterile rate in test cross and sib- cross offspring. Through repeative tests, we round that the frepuency ofnon- to-one family was around 13 percent. It is impossible to explain this complicated phenomenon of fertility separation by only using the theory of single gene be a complicated group, and it is necessary to further our study on all of these different separation rates.
