Abstract
Fatty acid distribution of groundnut (Arachis hypogaea) genotypes (228 in 1984 and 298 in 1985) grown at Gainesville and Marianna (Florida) was determined by gas-liquid chromatography. A wider range in fatty acid composition, especially in oleic and linoleic acids, was found among these genotypes than reported previously for the species. Two closely related experimental lines (435-2--1 and 435-2--2) had 80% oleic and 2% linoleic acid, with iodine values of 74. For the Florida breeding lines, iodine values of the oil ranged from 74 to 107 and the oleic/linoleic ratios from 0.9 to 35.1, compared to 95 and slightly less than 2, respectively, for Florunner. The oleic acid content of different experimental lines ranged from 37% to 80% and the linoleic acid content from 2% to 43%. It is suggested that the magnitude of this variability should permit the development of cultivars with a range of oil composition for various nutritional and industrial purposes. All the oil quality factors studied were highly significantly affected by genotype, and all but 3 of the factors were significantly affected by season.
