Character association studies in different fatty acid composition of groundnut (Arachis hypogaea L.)

Experiments were performed on peanut (Arachis hypogaea L.) to determine the correlation between the concentration of oleic acid and that of the other fatty acids by investigation of 90 peanut mutants lines of GPBD-4. In this experiment, oleic acid content was comprehensively evaluated in relation to other fatty acids. The highest correlations were noted for oleic and linoleic acids (r=-00.95) and for oleic and palmitic acids (r=-00.85). A positive relationship occurred between oleic acid and eicosenoic acid and inverse relationships occurred between oleic and behenic, arachidic, stearic, and lignoceric acids. Oleic acid positively correlated to the ratio of unsaturated to saturated fatty acids (r=0.83), whereas O/L ratio had significantly positive correlation with oleic acid and significantly negative correlation with linoleic acid
