This study was a replication of the study conducted last year to confirm the previous results. Freshly harvested groundnut pods were collected from five farmers' fields in Kalasin province. Seeds were dried to less than 7 % m.c. and stored in gunny bags lined inside with double layer plastic bags. For each seed lot, one part was kept at the farmer' house, and the other part was kept at KKU. Seed samplings were taken bimonthly for a period of 8 months for quality testings. During 8 months in storage, seed moisture content fluctuated only slightly. Significant differences in germination percentages were found among seed lots. The initial germination percentages ranged from 75-89 % indicating varying quality of seeds from different farmers. Most of the seeds maintained good viability for 6 months, but the germination percentage declined to below minimum standard (70 %) after 8 months. Electrical conductivity was found to show a strong negative correlation (r= -0.81** ) with germination percentage. The aflatoxin analysis showed no evidence of its production in all seed lots.
