Oil composition of diverse groundnut (Arachis hypogaea L) genotypes in relation to different environments

Bansal, U.K. and Satija, D.R. and Ahuja, K.L. (1993) Oil composition of diverse groundnut (Arachis hypogaea L) genotypes in relation to different environments. Journal of the Science of Food and Agriculture , 63 (1). pp. 17-19.

| Preview


Ten groundnut genotypes from each of 3 growth habits (Spanish bunch, Virginia runner and Virginia bunch) were evaluated for seed oil content and fatty acid composition in 4 environments (2 soil types and 2 years) at Ludhiana. Oil content was independent of growth habit, while differences in fatty acid contents were related to the growth habit. Both traits were significantly influenced by environmental fluctuations. Oleic acid concentration was highest in Virginia runner genotypes, followed by Virginia bunch, and was lowest in the Spanish bunch type. This trend was reversed with respect to linoleic acid concentration. Virginia runner genotypes, having a higher oleic:linoleic acid ratio, yielded a low iodine value oil and had a longer shelf-life. The genotypes with Spanish bunch type of growth habit possessed a higher linoleic acid content and can be used as a source of refined oil.
