ABSTRACT
The variability studies were done for different fatty acid in groundnut during kharif 2008 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The experimental material comprised of mutant lines derived from TPG-41 cultivars with 0.5% EMS and gamma rays (200Gy and 300Gy) treatments. The fatty acid profile was determined by near infrared reflectance spectroscopy (NIRS). Variability in fatty acid profile, especially in oleic and linoleic acids, was found widely among the mutants, while other fatty acids showed minor variation. The oleic acid content of the experimental material ranged from 46.98-62.98% and linoleic acid content ranged from 11.39to 28.48%. The O/L ratio, which is an index of oil stability, was ranged from 1.36- 4.90. The Oleic acid and linoleic acid were significantly negative correlation, whereas O/L ratio had significantly positive correlation with oleic acid and significantly negative correlation with linoleic acid.
