In the paper results of an experimental study of the change in winter wheat and winter barley frost resistance as related to damping off conditions are presented. As influenced by the length of damping off conditions effect on the plants, their resistance was found to distinctly reduce. Thus critical temperature of winter killing in winterhardy winter wheat and winter barley varieties was observed after 60 days of the crops remaining under damping off conditions to reduce - by 6-7 degrees C, in mediom winterhardy varieties - by 6-9 degrees C, whereas in winter wheat and winter barley varieties with narrow base of winter hardiness - by 7-12 degrees C.
