Fertility-restoring genes, Rfv1, Rfm1 and Rfn1, respectively, for the male sterile cytoplasms of Aegilops kotschyi, Ae. mutica and Ae. uniaristata to common wheat were located on the same locus of Pavon wheat 1BS arm. The male sterile cytoplasm (plasmon) and the fertility-restoring gene are essential genetic components for breeding hybrid seed crops. This article represents information on the genetic similarity of three Aegilops plasmons usable as the male sterile cytoplasm for hybrid wheat and provides an evidence on the possible genetic unity of three fertility-restoring genes reported for these plasmons by their genetic mapping using the 1BS-1RS recombinant lines of Pavon 76 wheat on to a single subsegment of the 1BS chromosome arm less than 2.9 cM in size: the locus is designated Rf (multi) , meaning "Restoration of fertility in multiple CMS systems". Unresolved problems were discussed in the use of the present cytoplasmic male sterility-fertility restoration system for hybrid wheat breeding.
恢复育性基因 Rfv1、Rfm1 和 Rfn1 分别位于普通小麦的 1BS 臂上，与 Aegilops kotschyi、Ae. mutica 和 Ae. uniaristata 的雄性不育细胞质同源。雄性不育细胞质（质体）和育性恢复基因是杂种种子作物育种的重要遗传组成部分。本文介绍了三种 Aegilops 质体作为杂交小麦雄性不育细胞质的遗传相似性，并提供了证据表明，通过对 Pavon 76 小麦的 1BS-1RS 重组系进行遗传作图，这三种质体的三个育性恢复基因可能具有遗传统一性，其大小不到 2.9cM：该基因座被指定为 Rf（多），表示“在多个 CMS 系统中恢复育性”。讨论了在利用目前的细胞质雄性不育-育性恢复系统进行杂交小麦育种时存在的未解决问题。
