Breeding for lipid composition in corn

Breeding for lipid composition in corn - United States of America : John Wiley & Sons ; American Oil Chemists' Society, 1975.
Large genetic diversity is available in corn (Zea mays L.) for alteration of its lipid composition. Mass selection has produced strains ranging from 0.4–17% oil with genetic variability still existing in the high oil version. High oil hybrids (7–8% oil) with yields equal to those of commercial hybrids (4% oil) have recently been developed. In feeding trials at the University of Minnesota, pigs made more efficient gains on high oil corn. Oleic and linoleic acids usually make up 80–90% of the fatty acids of corn oil. Screening of corn lines has revealed a range for linoleic acid of 25–71% and for oleic acid of 20–60%. Although the genetics of fatty acid synthesis have not been completely elucidated, breeding of corn with selected unsaturation should be possible. Fatty acid placement within the triglyceride molecule also may be subject to genetic modification in corn.
