Abstract
Nine varieties or strains of Spanish type peanuts were grown in the National Variety Test in Georgia and Oklahoma with and without irrigation for two growing seasons. The oil of sound kernels was analyzed for fatty acid composition. Although no consistent pattern was found, in general, variation in fatty acid composition due to variety was much less in Oklahoma than in Georgia for both the irrigated and nonirrigated peanuts. Also, location effect and soil moisture conditions gave higher percentages of palmitic and oleic with a lower percentage of linoleic in the Georgia samples and in the nonirrigated samples from both locations. Several significant first and second order interactions with the three major fatty acids involving variety, location, and soil moisture conditions were observed.
