ASSESSMENT OF COLD TOLERANCE IN RICE VARIETIES UNDER KARAKALPAKSTAN CONDITIONS

This study evaluated the cold tolerance of rice variety samples under Karakalpakstan conditions in laboratory settings. Seeds were stored in a thermostat at +10 °C, and germination rates were determined as percentages after 10 and 15 days. According to the results, Sanam, D-15 (D-158), and Guliston varieties showed high tolerance in cold conditions (75– 86%), while D-4 (14-04-3) had the lowest indicator (54%). These results demonstrate that certain varieties possess stable germination capacity even under low temperature conditions, serving as an important resource in breeding processes for creating varieties adapted to cold climate conditions.
