This experiment was carried out to know the adaptability and forage production and quality of corn hybrid for silage at paddy field of Chungnam region from 2008 to 2009. Among agronomic characteristics, 'Kangdaok' and 'Kwangpyongok' hybrid were somewhat strong for waterlogging and good stay green, lodging, disease and insect resistance. The dry matter yield of 'Kangdaok' and 'Kwangpyongok' hybrid were the highest among korean corn hybrids. Among introduced hybrid, 'P32T83' hybrid was strong for lodging and insect resistance, and had lower ear height and high Brix (B°, %). The dry matter yield of 'P32T83' and 'P32P75' hybrid were 20,150 kg/ha and 20,500 kg/ha, respectively. The 'P32P75' hybrid was high as 73% in vitro dry matter digestibility (IVDMD) and good stay green. The result of this study indicated that 'Kangdaok', 'Kwangpyongok', 'P32T83' and 'P32P75' hybrid could be recommended as having good characters according to production, waterlogging tolerance, stay green, disease and insect resistance at paddy field in the middle region of Korea.
