Frost damage is very important especially for Eastern Europe, but in some winters this aspect is of interest also for larger areas of Europe. The effect of the temperature at the crown level (considered as a function of snow and air temperature, Aase and Siddoway, 1979) it is better estimated if the physiological condition of the plant (hardening index) is taken into consideration. The algorithms for simulation of phenology, snow layer thickness, hardening, and frost damages from an older version of CERES Wheat (Ritchie, 1991) were transcribed in VBA and integrated into a system using the weather data base from CGMS (about 4000 grids of 50 x 50 km, starting from 1975) and crop calendars specific for each main agricultural area. In this presentation, the influence of phenology and cultivar dependent frost resistance per se is discussed, as well as the overview of the frost damages simulated for the considered period.
