摘要
汕优６３Ｆ２结实率分离不符合典型的正态分布。连续估计法表明，结实率在３０％以下时，估计出２对恢复基因，表明明恢６３具有２对基因可恢复野败胞质雄性不育性。
The segregation of seed set in (Shanyou 63 X Yebai) F 2 was found to be in inconsistency with the typical normal distribution. A study with the continuous estimation method showed that two restoring genes are involved when seed set percentage is lower than 30%. It is therefore speculated that Minghui 63 possesses two pairs of restoring genes which restore the fertility in the csm lines of the Yebai (wild abortive) system.
