Abstract: Significantly related to vernalization characteristics and freezing resistance of wheat, but has no relation with the frost resistance, so in frost prone areas to promote strong frost winter and semi winter varieties and can not completely eliminate or avoid frost damage. By the field investigation analysis of frost resistance varieties more general conclusions, but by using the artificial frost box can not only accurate identification of winter wheat frost resistance changing period, namely low temperature sensitive phase, but also the identification method of frost resistance of winter wheat varieties force more convenient. Based on the domestic and foreign research results, put forward a series of countermeasures： breeding resistant varieties, optimizing the layout of planting; seedling cultivation, enhancement of winter wheat frost resistance; By means of INA bacteria and gene engineering, improved varieties of frost resistance.
