Characteristics of sweet (sugary, su) and super sweet (shrunken-2, sh2) corn seeds shelled by different threshing methods at different moisture content status were studied. Hybrid seeds of a su (Early Sunglow × Golden Cross Bantam 70, GCB 70) and a sh2 (Xtrasweet 82 × Fortune) were dried to moisture content of 12, 15, 18, and 21%. Hand shelling did not give any mechanical damages to seeds, while an electrical corn thresher gave some visible mechanical damages. The emergence rate of hand shelled seeds was higher than that of machine shelled seeds by 6~14% for a su and by 9~18% for a sh2 hybrid depending on seed moisture contents in cold test.
