对Ｋ、Ｌ、Ｓｈ、Ｔ型４类小麦雄性不育系杂种Ｆ１恢复度分析表明：①４类细胞质均存在不同程度的不良效应；②不育系易恢复性能为Ｋ＞Ｌ≥Ｓｈ＞Ｔ型；③Ｋ型不育系恢复度高的一个重要原因在于小穗中部小花结实性好；④４类不育系的恢复度均与穗粒数有重要相关关系；⑤４种细胞质类型对筛选高恢复度杂种Ｆ１具有各自不同的要求；⑥研究Ｋ、Ｌ、Ｓｈ型恢复度时，利用国际法表示恢复度较为合理
The results showed that: ① The cytoplasm of class 4 had different degrees of adverse effects; ② The easy recovery of CMS was K> L≥Sh> T ; ③K type sterile line is a high degree of recovery is an important reason for the fine spikelets in the middle of good solidity; ④Stypes of the four kinds of male sterile lines have a significant correlation with grain number per spike; ⑤4 kinds of cytoplasmic types of high recovery hybrids F1 have their own different requirements; ⑥ study K, L, Sh recovery degree, the use of international law that restoration is more reasonable
