Effect of Cultivar and Growing Location on Lipid Content and Fatty Acid Composition of Peanuts (Virginia Market Type)

Abstract

In order to evaluate the effect of cultivar and growing location on lipid content and fatty acid composition of peanuts of Virginia market type, four infraspecific cross-origin cultivars between Virginia and Spanish botanical types were grown on the Prefectural Agricultural Experiment Stations of Aomori (lat. 40°38'N., long. 141°21'E.), Chiba (lat. 35°35'N., long. 140°20'E.), and Miyazaki (lat. 31°38'N., long. 131°48'E.) in Experiment 1, and two infraspecific cross-origin cultivars and two Virginia botanical cultivars were grown on the Prefectural Agricultural Experiment Stations of Chiba, Aichi (lat. 34°44'N., long. 137°26'E.), and Nagasaki (lat. 32°49'N., long 130°1'E.) in Experiment 2. Their constituents of the seeds were analyzed. Among the cultivars, significant differences were observed in oleic and linoleic acid contents in Experiment 1 and 2 and further in palmitic, behenic, and lignoceric acid contents in Experiment 2. The infraspecific cross-origin cultivars showed both fatty acid compositions of Virginia and Spanish botanical types. As to the growing location, it had a tendency that the lower the latitude, the more the stearic, oleic, and arachidic acid contents and the less the linoleic, eicosenoic, behenic, and lignoceric acid contents. Among the locations, significant differences were observed in stearic, oleic, linoleic, arachidic, and behenic acid contents in Experiment 1 and 2 and further in eicosenoic and lignoceric acid contents in Experiment 1.
