Background: Cytoplasmic male sterility in flowering plants is a convenient way to use heterosis via hybrid breeding and may be restored by nuclear restorer-of-fertility(Rf) genes. In most cases, Rf genes encoded pentatricopeptide repeat(PPR) proteins and several Rf genes are present in clusters of similar Rf-PPR-like(RFL) genes. However, the Rf genes in cotton were not fully characterized until ***: In total, 35 RFL genes were identified in G. hirsutum, 16 in G. arboreum, and 24 in G. raimondii. Additionally,four RFL-rich regions were identified; the RFL-rich region in Gh05 is the probable location of Rf-PPR genes in cotton and will be studied further in the future. Furthermore, an insertion sequence was identified in the promoter sequence of Gh05 G3392 gene in the restorer line, as compared with the CMS-D2 line and maintainer lines. An InDel-R marker was then developed and could be used to distinguish the restorer line carrying Rfl from other genotypes without the Rf1 ***: In this study, genome-wide identification and analysis of RFL genes have identified the candidate Rf-PPR genes for CMS in Gossypium. The identification and analysis of RFL genes and sequence variation analysis will be useful for cloning Rf genes in the future and also for three-line hybrid breeding in cotton.

选用7个不同细胞核背景的三裂棉细胞质雄性不育系(CMS-D8)和1个具有强恢复力的哈克尼西棉雄性不育恢复系ZHR142作为亲本,配制7个杂交组合,分别种植在西北内陆棉区的新疆阿拉尔和黄河流域棉区的河南安阳,对亲本及其杂交组合F_(1)、F_(2)和对照的产量及其构成因素进行优势分析。结果表明:尽管F_(2)产量优势较F_(1)有所衰退,但仍有部分组合如3、6和7的F_(2)籽棉产量和皮棉产量表现较好;大部分CMS-D8胞质F_(2)产量竞争优势减退主要是由于铃重的降低;部分组合如1、3、6和7的不同世代在2个生态点具有一定的产量优势,尤其是组合6和7的F_(1)、F_(2)产量在阿拉尔生态点均表现为正向竞争优势。本研究结果对D8胞质不育三系杂交棉选育及其F_(2)利用具有一定的指导意义。
