Abstract
Several sunflower (Helianthus annuus L.) mutants with altered seed fatty acid composition have been obtained. These mutants were selected after mutagenesis of sunflower seeds with X-rays, ethyl methane sulfonate (EMS) and sodium azide. The screening was performed at the level of the M2 and M3 generations, where individual seeds were analysed for fatty acid composition by GLC [1]. All mutants selected had higher saturated fatty acid content than the normal sunflower. Four had high stearic acid content and two high palmitic acid content. The high palmitic mutants are similar to that reported by Ivanov [2] and were obtained in both normal and high oleic acid backgrounds.
