Abstract: Creating cold-resistant varieties in wheat breeding programs is one of the most difficult tasks because several genes are involved. The main difficulty in creating cold-resistant varieties in breeding is usually the relationship between high cold tolerance and low yield and late ripening. Therefore, the purpose of selection is not to maximize cold tolerance, but to create varieties that can withstand the minimum temperature for a particular area. One of the important features of the regionalized wheat varieties in the country is their tolerance to cold and adverse winter conditions, as in some years, due to the very low temperatures, the germination of germinated seedlings increases and seedlings become sparse.
