The seeds of RHRG-6021, RHRG- 6083, TAG-24 and JL-501varieties of groundnut were stored and evaluated for oil content (%), protein content , Iodine value of oil, free fatty acid of oil, total polyphenol, saponification value and total soluble sugar. The genotype RHRG-6021 recorded highest oil content (51.65 %). The storage container showed non-significant result for oil content, iodine value, free fatty acid content, protein content and total polyphenol content of groundnut. The highest iodine value was at 270 days of storage in all genotypes of groundnut. The significant differences was observed in free fatty acid content in all four genotypes of groundnut, and among four, JL-501 genotype recorded highest free fatty acid content at 270 days of storage. The higher protein content was recorded in genotype TAG-24 (24.85 %) at start of storage. The groundnut genotype RHRG-6083 exhibited highest polyphenol content at 270 days of storage (0.544) which has increased subsequently during storage. The highest saponification value was observed in JL- 501 (198.2) at 270 days of storage. The saponification value in polylined HDPE bag showed higher value than that in HDPE bag. RHRG-6021 genotype has highest total sugar (7.36) at initial stage, which decreases subsequently. The genotypes stored in polylined HDPE bag had higher total sugar content than HDPE bag.
