摘要
来自ＣｈｉｎｓｕｒａｈＢｏｒｏⅡ水稻雄性不育胞质ｃｍｓ－ｂｏ，其恢复可育受１对显住Ｒｆ－１基因控制，该基因属ｆｌ－ｐｇ１连锁群。Ｒｆ－１座位上有４个效应不同的复等位基因。来自野败水稻雄性不育胞质ｃｍｓ－ＷＡ，在一些试验中其恢复可育至少有２对独立的恢复基因，它们的互作效应随不同组合而异；在其它试验中，恢复性受单基因、多基因、隐性微效基因或修饰基因控制或调节。一些恢复基因和符号已由水稻基因符号、命名和连锁群委员会认定。
The fertility restoration for cms-bo, a cytoplasmic male-sterile rice derived from ChinsurahBoro II, is governed by a dominant Rf-1 gen, one of the four alleles at a locus on fl-pgl linkage group.There are other three alleles at the same locus, but they differ in their interactions with the respective cyto-plasms. Restoring for cms-WA derived from ″ wild abortive″ rice is found in some experiments to be con-trolled by at least two independent loci with different interactions with parent combinations. In other experi-ments, however,it could be governed by a single dominant gene, multiple genes, minor recessive genes,ormodifying genes. Several restoring loci and their symbols have been registered by the Committee on Gene Sym-bolication, Nomenclature and Linkage Groups.
