Abstract
In order to select maize varieties with strong frost hardiness,five maize varieties were chosen to compare ability of frost hardiness by suffering from nature frost and simulation frost experiment.The results showed that Nongda 108 had the strongest ability to freezing hardiness and Shandan 931 had the weakest ability to freezing hardiness among 5 maize varieties.The lower temperature and the longer frost lasted,the more serious damage maize would have.The nearer maize approaching maturity period,the stronger the maize ability to freezing hardiness would have.
