Collaborative Project: Brassica wild species as a new genetic source for rapeseed breeding - Subproject 2
Project
Project code: 2814302307
Contract period: 01.11.2007
- 31.01.2011
Budget: 178,004 Euro
Purpose of research: Experimental development
Rapeseed has developed in evolution by a spontaneous hybridization between turnip rape and cabbage. For breeding purposes it is possible to produce 'resynthesized rapeseed' by artificial hybridization between these two species. As cabbage parent vegetable types have been used so far. However, there exist several wild species related to cabbage. In this project such wild species were for the first time used to broaden the genetic diversity of oilseed rape. It could be shown by molecular markers (AFLP) that these new resynthesized lines represent a genetic diversity not present in the worldwide breeding material or in older resynthesized lines. The material was tested at 9 locations in Germany, France and UK. It has a low winter hardiness and a low oil content. However when crossed with adapted genotypes, the performance nearly reaches the best present cultivars. Therefore the new resynthesized lines will be valuable to broaden the genetic variation available for oilseed rape breeding.
