The article discusses the issue of frost resistance of varieties and samples of winter wheat sown at different depths, in the extreme conditions of Karakalpakstan. Both a decrease and an excessive deepening of sowing leads to a significant decrease in their resistance to low temperatures, which negatively affects their subsequent survival in the spring-summer period. On the basis of the data, 2 varieties were selected, they turned out to be frost-resistant and differed in good yield and other valuable traits in comparison with the zoned varieties. They were transferred to the State Commission for Variety Testing of Agricultural Crops, under the name "Chimbay" and "Aral".
