Abstract
A comparison was made of the content of total and some individual fatty acids in grains of nine barley varieties grown at six sites in Belgium. The varieties represented six‐ and two‐rowed winter types and two‐rowed spring types. The results showed that the winter types contain more linolenic acid (C18 : 3) than spring types and that six‐rowed barleys have less total fatty acids than two‐rowed barleys, due mainly to a low concentration of palmitic (C16:0), oleic (CI8 : 1) and linoleic (C18 : 2) acids. Analysis of variance showed that fatty acid content is affected by both the genotype and the environment and multiple regression analysis suggested that weather conditions before and after flowering affected lipid composition.
