Abstract

Five peanut (Arachis hypogaea L.) genotypes, Southern Runner, Dixie Runner, Florunner, UF82206, and UF714021, were grown for three years, 19821984, near Gainesville, Florida without fungicide applications. Three digging dates, averaging 105 days after planting (DAP), 118 DAP, and 132 DAP, were used each year to determine the effects of early harvest as a management practice for peanut production under leafspot pressure. The different digging dates had no effect on fatty acid composition of the five genotypes, and had only minimal effect on the oil content and iodine value. The largest oil quality differences in this study were due to differences among genotypes and year-to-year variation.
