This study investigated on the chemical components, quality characteristics, antioxidant compounds, and activity of maize hybrids according to the cultivar, and breeding maize seeds crossed with seed and pollen parent. The moisture, crude fat, crude ash, crude protein, carbohydrate, and amylose contents of maize hybrids were significantly different among cultivars, and seeded and pollinated maize. The L-, a- and b-value of maize hybrids were 39.81~47.21, －0.01~0.55 and 5.85~18.47, respectively. Water binding capacity, water solubility index and swelling power were 123.29~153.32, 4.69~5.76 and 20.11~21.47%, respectively. The phenolic compounds and radical scavenging activity of maize hybrids were significantly different among cultivars, and seeded and pollinated maize. Total polyphenol and flavonoid contents of maize hybrids were 1,335.41~1,876.29 μg/g and 184.24~453.95 μg CE/g, respectively. The DPPH and ABTS radical scavenging activities were 171.75~239.16 and 299.44~364.09 mg TE/100 g, respectively. As a result, it could be used as a basic data for cultivating phenol compounds and antioxidant activity in maize breeding.
