  • Method of selecting corn embryos
    Patent number: 10945390
    Abstract: The present invention relates to a viability-retaining method of selecting corn embryos having a desired trait, said method comprising extracting embryos, removing associated non-embryogenic tissue or DNA from the exterior of the embryo; and extracting DNA directly from the embryo. The invention surprisingly shows that germinating embryos sampled directly for their DNA content are capable of continuing the germination process to form normal seedlings.
    Type: Grant
    Filed: July 6, 2016
    Date of Patent: March 16, 2021
    Assignee: Syngenta Participations AG
    Inventors: William Paul Bullock, Ulrich Stephan Hannappel, Katie Marie Hunter

  • Non-disruptive DNA isolation from corn seeds
    Patent number: 10011828
    Abstract: This invention relates to systems and process for isolating DNA from biological materials such as seeds while retaining a viable seed for further use. The seed from which the DNA is isolated remains viable and is used or discarded based on the DNA analysis of the seed soak solution. The seed soak solution can have substantially all of the confounding maternal DNA from the seed eliminated from the seed soak solutions by employing intact seed pretreatments. This method is particularly useful for maize seed.
