MAIZE CYTOPLASMIC MALE STERILITY (CMS) C-TYPE RESTORER RF4 GENE, MOLECULAR MARKERS AND THEIR USE.

摘要

This disclosure concerns high resolution mapping and candidate gene cloning of Rf4, a maize restorer of fertility gene that restores fertility to C-type cytoplasmic male sterility. The disclosure also relates to molecular markers that are tightly linked to, or reside within, the Rf4 gene. In some embodiments, methods are provided whereby hybrid seeds may be produced from crosses of a male plant comprising nucleic acid molecular markers that are linked to or that reside within the Rf4 gene and a female plant carrying C-type CMS.
