Development of resynthesized oilseed rape (Brassica napus) with improved resistance against Verticillium longisporum
Oilseed rape is today the most important oil crop in Europe. The importance of rapeseed oil as a renewable raw material has ledto an increase in cultivation area in Germany upto 1.4 million ha in Germany in 2006, and production of up to 2 million ha is projected for the coming decades. Because of the relatively short crop rotation and the increased area under rapeseed cultivation,diseases can be a significant problem. Verticillium wilt of oilseed rape is caused by the host-adapted pathogen Verticillium longisporum and can cause yield loss of up to 50％. Verticillium longisporum poses a threat to Sweden, Denmark, Great Britain and in the north of Germany. Since no certified fungicides for V.longisporum are available this disease is expected to be one of the major problems for rapeseed production in Northern Europe in the coming decades. The aim of this study was to identify new resistance sources among Brassica rapa and Brassica oleracea accessions and introduce these into the B. napus gene pool via resynthesized rapeseed.
