“…The average values for each fatty acid of the Corn Belt corn grown in France (data not shown) were within two percentage points of the average values reported by Tan and Morrison for com grown in France ( 19). The fatty acids of the Com Belt com grown in France also were similar to data shown in Table 1, except the French-grown com was 1.3 percentage points less saturated than the Iowa-grown com, with most of the difference being made up of 18: 1.…”

The fatty acid composition of corn oil can be altered to meet consumer demands for "healthful" fats (i.e., lower saturates and higher monounsaturates). To this end, a survey of 418 corn hybrids and 98 corn inbreds grown in Iowa was done to determine the fatty acid composition of readily-available, adapted, elite corn breeding materials. These materials are those used in commercial hybrid production. Eighty-seven hybrids grown in France (18 of which also were grown in lowa) were analyzed to determine environmental influence on fatty acid content. The parents of the hybrids and the inbreds were classified in one of four heterotic groups: Lancaster, Stiff Stalk, non-Lancaster/non-Stiff Stalk, and Other.t-Tests and correlation analyses were performed with statistical significance accepted at a level ofP≤0.05. The findings showed a wide range of fatty acid profiles present in adapted, elite corn breeding materials with ranges for each fatty acid as follows: palmitic acid, 6.7-16.5%; palmitoleic acid, 0.0-1.2%; stearic acid, 0.7-6.6%; oleic acid, 16.2-43.8%; linoleic acid, 39.5-69.5%; linolenic acid, 0.0-3.1%; and arachidic acid, 0.0-1.0%. Small amounts of myristic acid, margaric acid, and gadoleic acid also were found. Three lines had total saturates of 9.1% or less. Thirty-six of thet-tests involving hybrids showed significant differences among heterotic groups. There were small but significant correlations among protein, starch and oil content and the amounts of several fatty acids. Results from the corn grown in France vs. lowa demonstrated a large environmental effect that overwhelmed the genetic differences among lines. This study shows that for some attributes, a breeding program involving adapted corn breeding materials might produce the desired oil. Other types of oil (such as high-oleic) would have to be produced in a different manner, for example, by a breeding program with exotic breeding materials.

“…Tan and Morrison (1979) reported that the levels of this fatty acid in the pericarp, germ and endosperm fractions were: 19.4-24.7%, 10.6-12.0% and 24.7-27.5%, respectively. However, Moreau, Singh, Nuñez, and Hicks (2000) reported that the germ, fibre and aleurone fractions had similar proportions of palmitic acid.…”
