普通小麦粗厚山羊草细胞质的野林26表现为光周期敏感型细胞质雄性不育。该异源细胞质系在长日照条件下（15 h光照）几乎完全雄性不育，但在短日照条件下（14.5 h光照）高度雄性可育。T.普通小麦具有相同细胞质的中国春不表达PCMS。常规分析和端体分析表明，中国春的育性恢复主要受位于7B染色体长臂上的一个显性基因（Rfd1）控制，育性恢复水平的改变涉及大量的修饰基因。Rfd1基因的功能在孢子体中表达。在Ae的存在下，携带和不携带该基因的两种花粉粒之间存在轻微的联系。厚质细胞质。
Triticum aestivum cv. Norin 26 with Aegilops crassa cytoplasm shows photo-period-sensitive cytoplasmic male sterility (PCMS). This alloplasmic line is almost completely male sterile under a long-day condition (15 h light period), but highly male fertile under a short-day condition (14.5 h light period). The alloplasmic line of T. aestivum cv. Chinese Spring with the same cytoplasm does not express PCMS. Conventional and telosomic analyses revealed that the fertility restoration manifested by Chinese Spring is controlled mainly by a single dominant gene (designated Rfd1) located on the long arm of chromosome 7B, and that a large number of modifiers are involved in modifying the level of fertility restoration. The function of the Rfd1 gene is expressed sporophytically. A slight certation was observed between the two types of pollen grains, one carrying and the other not carrying this gene, under the presence of Ae. crassa cytoplasm.
