An experiment was conducted to characterize the seed vigour of sweet (su) and super sweet (sh2) corn seeds stored at different temperatures and relative humidities (RH). Hybrid seeds of Early Sunglow × Golden Cross Bantam 70 (su) and Xtrasweet 82 × Fortune (sh2) were stored at different temperature (5 and 15℃) and RH (70 and 85%) for 10 months. Results of the experiment show that seed deterioration of super sweet corn was much faster than that of sweet corn under all storage conditions. Germination rate of sweet corn seeds at 25℃ and emergence rate in cold test showed similar patterns.
