Non-Peer ReviewedAn interactive web-based model for estimating winter survival in cereals has been developed for
use by farmers, extension workers, and researchers. The model is based on a series of equations
that describe acclimation, dehardening, and damage due to low-temperature stress that are
consistent with recent interpretation of low-temperature gene regulation. Low-temperature
tolerance is estimated on a daily basis relative to stage of phenological development and cultivar
cold hardiness potential. The model has been field validated for cereals in Saskatchewan and has
been used in the simulation of over wintering for a wide range of species. Because it complies
with the known low-temperature responses of cereals and is fully interactive, it can be used as a
teaching tool that allows production risks, cause-and-effect processes, and genetic theories to be
systematically investigated
