Seeds of linseed ( Linum usitatissimum L.) cultivars ‘Raulinus’ and ‘Bionda’ were treated mutagenically with ethyl methanesulfonate (EMS) in order to broaden the variation of fatty acid composition in the seed oil and to select mutants with reduced linolenic acid (C18: 3) content. The M 2 generation was evaluated for fatty acid composition of the oil. Genetic variation for unsaturated fatty acids was demonstrated to be extended in the M 2 generation as compared to the controls. Finally in the M 5 generation of cv. ‘Raulinus’, lines with reduced C18:3 (< 40% vs. 55%) and correspondingly increased linoleic or oleic acid contents, respectively, could be selected. These mutants proved to be genetically stable as demonstrated by parent‐offspring (M 4 /M 5 ) regression.
