Taking the method of artificial inoculation, the resistance of 920 maize hybrids to head smut were i-dentified and evaluated.The result showed that 1.3% maize hybrids were highly resistant, 10.1% maize hybrids were resistant, 12.6% maize hybrids were moderately resistant, 62% maize hybrids were susceptible and 20% maize hy-brids were highly susceptible.Test of maize hybrid in different areas and types showed that 37.8% later-maturing maize hybrids and 23.3% succulence maize hybrids, 18.5% early-maturing maize hybrids, 17.5% summer-planting maize hybrids and 16.7% special-early-maturing maize hybrid, 8.6% waxy maize hybrids and 5.4% sweet maize hy-brids were moderately-highly resistant.Among 160 authorized maize hybrids, there were 4 highly resistant, 11 resis-tant and 19 moderately resistant.
