Usually, the seed oil of Brassica oleracea, i.e., cabbages, cauliflower, kohlrabi, kales, etc., is characterised by a high content of erucic acid. However, it has been possible to identify individual plants in accessions of B. oleracea conv. capitata being nearly free of erucic acid. Genetic analysis of the progeny has revealed that erucic acid content in this diploid Brassica species is under monogenic control and that the low-erucic trait is true-breeding. With regard to the molecular basis of erucic acid genetics our studies support the hypothesis that biosynthesis of erucic acid is controlled through the expression of the elongase condensing enzyme (beta-ketoacyl-CoA synthase), which is encoded by gene(s) or alleles homologous to the FAE1 gene of Arabidopsis thaliana.
