The freshly harvested groundnut pods of different varieties viz., VRI 2, VRI 6, VRI 7, VRI 8, CO 6, CO 7 TMV 7 and TMV 13 were collected and dried to 9% moisture content, packed in cloth bag without any pod treatment and stored under cold (4 ± 2°C) and ambient storage condition (28 ± 2°C). The seeds were evaluated for the seed quality characters at monthly interval upto 12 months revealed that the varieties VRI 7 and TMV 13 showed higher germination than other varieties irrespective of storage condition. With reference to the storage conditions, seeds stored in cold conditions recorded higher germination than the ambient condition stored seeds irrespective of varieties
