摘要： The present disclosure provides a method for selecting a plant comprising a functional restorer gene for maize S-type cytoplasmic male sterility comprising the steps of (a) screening a population of plants for at least one marker nucleic acid, wherein the marker nucleic acid comprises an allele linked to the functional restorer gene for maize S-type cytoplasmic male sterility; (b) detecting the marker nucleic acid; (c) identifying a plant comprising the marker nucleic acid; and (d) selecting the plant comprising the marker nucleic acid, wherein the plant comprising the marker nucleic acid further comprises the functional restorer gene for maize S-type cytoplasmic male sterility. The present disclosure also provides methods for restoring fertility in a progeny of an S-type cytoplasmic male sterile plant and methods for transferring an Rf3 gene into a progeny plant.
