Corn seed storability and accelerated aging in the humid tropics were studied by producing the seeds of varieties Nakornsawan 1 and Suwan 2. After harvest the seeds were stored in paper bags at room temperature for 12 months and were accelerated aged in nearly 100 percent relative humidity at 42, 43 and 44 deg C for 48, 72 and 96 hrs. Every three months the seeds were sampling for quality testing. Seed quality of each temperature and time of accelerated aging was correlated to the seed of 12 months open storage. These two varieties corn seeds at 8 percent moisture content could be open stored in the humid tropics for 9 months with more than 75 percent germination and equilibrium moisture content of 11 percent. Seedling growth rate decreased after 6 months seed storage. Accelerated aging at 42 deg C for 96 hrs could not be effectively evalate corn seed storability in the humid tropics but at 44 deg C for 96 hrs had a better correlation to the quality of seed open stored for one year.
