Defra project IF0189
Early F1 hybrid varieties of Brussels sprouts (released in the early 1980s in the UK) offered higher vigour, productivity and uniformity than open-pollinated varieties. They represent a source of useful genetic variation in a form which can be more rapidly incorporated into new elite varieties. Parental lines for early F1 varieties are often unavailable, making it difficult to regenerate fresh seed to ensure conservation in genebanks. This project assesses genetic variation in open pollinated and F1 hybrid UK Brussels sprouts and tests three regeneration protocols to see which offered the best balance between conservation of genetic diversity and resources required.
