  • Patent number: 11930756
    Abstract: A method of plant genetics and plant breeding including wheat plants carrying restorer of fertility genes specific to T. timopheevii CMS cytoplasm.
    Type: Grant
    Filed: May 28, 2021
    Date of Patent: March 19, 2024
    Assignee: LIMAGRAIN EUROPE
    Inventors: Pierrick Varenne, Jordi Comadran, Sébastien Specel, Mickaël Throude, Jérémy Derory
  • Patent number: 11737404
    Abstract: Disclosed is a method of producing hybrid seeds, in particular hybrid cereal seeds, comprising crossing a stand of shorter female (male sterile) plants (shorter than the fertile plants) with a stand of taller male fertile plants (taller than the sterile plants). The method comprises limiting the proportion of self-fertilized male seed in the final produced seed stock. In particular, the method limits the seed development on male plants after pollination to reduce or eliminate the proportion of self-fertilized male seed in the final produced seed stock. The method limits this proportion of self-fertilized male seed in the final produced seed stock, under a threshold value, preferably under a value to be compliant with a regulatory hybridity level. Limiting the seed stock of male plant comprises passing, at least once, a tool extending above the height of the shorter female plants, but below the level of the height of the taller male fertile plants, between anthesis, preferably end of anthesis, and harvest.
