Improvement of stem mold resistance of oilseed rape

Abstract: The German set of winter oilseed rape varieties does not contain any recognised resistance against the pathogen Sclerotinia sclerotiorum. Because of this, screening methods were developed to characterise a set of varieties provided by different breeding companies. These methods, including field experiments, a greenhouse screening study and a laboratory assay, were presented and a comparison of results given. Additionally the greenhouse screening and the laboratory assay were used to characterise wild Brassica species. By these means, possible sources of resistance should be identified.
