Mutagenesis has played a major role in the development of novel variation for the fatty acid profile of oilseed crops. Although the first successful experiments were started in the 70s, most of the achievements in this field have been reported during the 80s and 90s. This paper summarizes the role of mutagenesis in the modification of the fatty acid profile of oilseed crops, the genetic basis of such modifications, and the consequences for plant breeding.
