Identification of donors for effective restoration of male sterility based on cytoplasm of T. timopheevii and molecular characterization of P class PPR gene family as source of candidate genes for restoration (RESTORER)

Production of hybrid seeds using a cytoplasmic male sterility (CMS) system is successfully established in many crop species. In wheat, a male sterility system based on the cytoplasm of T. timopheevii is available, but effective restorer genes have yet to be identified. At the end of the project, a maximum number of two genes allowing the complete restoration of F1 seeds should be ready for use. Closely linked and diagnostic molecular markers will facilitate the efficient stacking of the restorer genes during breeding cycles. A candidate gene approach based on the P class PPR gene family will accelerate the screening of lines for restorer genes and enable the identification of effective restorers.
