Fatty-acid composition of oil from endosperm, scutellum, coleoptile-plumule, and coleorhiza-radicle kernel fractions of ten corn inbred lines was determined by gas-liquid chromatography. Significant differences were found among kernel fractions and inbred lines for palmitic, palmitoleic, stearic, oleic, linoleic, arachidic, and linolenic acids. All kernel fractions were significantly different from each other in oleic, linoleic, and linolenic acids. The endosperm oil was highest in palmitic, palmitoleic, stearic, and linolenic acids and lowest in oleic acid. The scutellum oil was lowest in palmitic, linoleic, and linolenic acids and highest in oleic acid. High negative correlation coefficients of -0.93 to -0.97 between oleic and linoleic acids were obtained for kernel fractions. Certain other correlation coefficients among fatty acids of kernel fractions were significant but were lower in magnitude. Fatty-acid composition of oil among fractions within inbred lines was more closely related among scutellum and embryo axis (coleptile-plumule and coleorhize-radicle) fractions than between endosperm and other fractions.
