[The influence of decreased temperatures on meiotic disorders in spring wheat].

An effect of low temperature (0-2 degrees C) on meiosis was studied in different varieties from various ecological zones. It is shown that the Mexican varieties are most sensitive to the effect of low temperature. The percentage of sterile pollen and disturbances in anaphase I in them are the highest. The local varieties with respect to these characters are more resistant to the effect of low temperature.
