| Summary: | Oil content and fatty acid composition profiles in grain of 18 proso millet accessions were investigated.The results showed that oil content in proso millet ranged from 2.54% to 4.00%,and averaged 3.71%.The major fatty acids detected were linoleic (18:2n6),oleic (18:1n9) and palmitic (16:0),ranging from 0.075 to 5.19,0.150 to 3.02,and 0.897 to 1.81 g/100 g,respectively.Minor fatty acids included palmitoleic,stearic,linolenic,arachidic,arachidonic,docosanoic and tetracosanoic acids.The unsaturated fatty acids (UFA) accounted for 82.1%～94.6% of the total oil.Both correlation analysis and principal component analysis indicated significant inter-relationships among ten fatty acids.Cluster analysis suggested that the fatty acid profile was significantly related to genotypes.
