Brassica : Harvesting the Genome, Diversity and Products

international research environment  with access to relevant genomic and trait information.

3.5.2.

Heterosis

The strong self-incompatibility within Brassica species leads to a natural outcrossing breeding system. Recurrent selfing tends to lead to inbreeding depresssion. The fixation of genetic variation in F1 varieties provides considerable advantages in terms of hybrid vigour, also known as heterosis. The natural variation, breeding material and experimental systems for Brassica provide an excellent opportunity to determine the genomic basis of heterosis, which is not yet fully understood.

3.6.

Non-food uses

There is considerable scope for increasing the added value from Brassica-based production. For oil-based products these include high-value lubricants, bio-fuels, plastics and composites, as well as fibre-based products.
