A set of twenty six segregating lines along with their parents (ICGV 06189 and Sunoleic 95R) were studied overseasons (kharif 2019 and summer 2020) at University of Agricultural Sciences, Dharwad to study the seasonal influence onoil quality and productivity parameters. Significant genetic variation was observed for productivity parameters and fattyacid components along with oil content and O/L ratio in both the seasons. Significant differences among genotypes, seasonsand their interaction was observed for majority of the productivity and fatty acid components. Oleic acid had significantpositive association with O/L ratio whereas, significant negative association with linoleic acid and palmitic acid during bothkharif and summer seasons. Non-significant correlation existed between oleic acid with all the productivity parametersduring both the seasons. Two lines each with higher oleic acid (line number 2 and 14) and higher pod yield (line number 10and 17) were identified during kharif season while three lines (line number 1,2 and 12) with higher oleic acid and nine lineswith higher pod yield were identified during summer season. The pooled analysis over seasons indicated one line (linenumber 2) superior for oleic acid across two seasons. The promising lines with high oleic acid and pod yield need to betested over locations and years for studying their stability.Key words: Fatty acid, Groundnut, Oil quality, Oleic acid
