  abstract  = {Erucic acid is a mono-unsaturated fatty acid that is naturally found in large quantities in seeds of rapeseed (Brassica napus L.) and other Brassica species. Erucic acid represents an important resource in the industry, however, due to its injurious effects on the heart muscle, this fatty acid is considered to be nutritionally harmful. Therefore, new high quality rapeseed cultivars were bred in order to eliminate the content of erucic acid in rapeseed oil at the end of the 20th century. In the breeding process, paper chromatography was used for the distinction between seeds with high and low content of erucic acid. Here, this outdated method was revised and optimized for educational purposes. By means of paper chromatography the qualitative content of erucic acid and four other unsaturated fatty acids was analyzed in rapeseed and linseed. The character 'erucic acid content', determined by two additive genes, can be used as a practical example of a phenotypic marker in school lessons, for instance, in the course 'achievement of plant breeding'. Thus, this qualitative analysis of erucic acid content enables the teacher to connect classical genetics with modern methods of plant genetics.},
