Diploid Inbreds For Fixation, and Unreduced GAmetes for Tetraploidy – A novel Fixation-Restitution Breeding method for potato

    Project: NWO project

    Project Details

    Description

    DIFFUGAT (Diploid Inbreds For Fixation, and Unreduced GAmetes for Tetraploidy – A novel Fixation-Restitution Breeding method for potato) aimed to develop an innovative potato breeding scheme. Self-compatibility (Sli-locus), Diploid pollen and desynapsis were studied.

    Potato breeding is complicated because of tetraploidy and outbreeding. While F1-hybrid breeding was proposed, this alternative uses of similar components, yet avoiding inbreeding depression. For society the speed of developing robust potato varieties with high resistance to pests and pathogens has increased, to lower use of pesticides, reduction of emissions during pesticide sprays and a more healthy environment.

    Description

    DIFFUGAT (Diploid Inbreds For Fixation, and Unreduced GAmetes for Tetraploidy – A novel Fixation-Restitution Breeding method for potato) beoogt innovative aardappelveredelingsschemas te ontwikkelen. Zelfcompatibiliteit (Sli-locus), diploïde pollen en desynapsis warden onderzocht.

    Aardappelveredeling is ingewikkeld vanwege tetraploïdie en uitteelt. Hoewel F1-hybriden ontwikkeld worden, gebruikt dit alternatief vergelijkbare componenten, maar vermijdt inteeltdepressie. Voor de samenleving is de snelheid van het ontwikkelen van robuuste aardappelrassen met een hoge resistentie tegen plagen en ziekteverwekkers toegenomen. Dergelijke hoog resistente rassen dragen bij aan een lager gebruik van bestrijdingsmiddelen en een gezonder milieu.
