Abstract

The study evaluated post-winter survival and phenological development of winter bread wheat accessions under the sharply continental conditions of Karakalpakstan. More than 150 accessions were screened in 2025–2026, and 50 were subjected to detailed observations. Post-winter survival ranged from 93.1 to 94.4%. Early developmental stages were relatively synchronized, whereas the main differences occurred at heading and full maturity. D-197 (D-205) D-196 and D-50 (D-77) D-21 D-133×Avoset (2) showed comparatively early generative development. D-50 (D-77) D-21 D-133×Avoset (2) combined 94.4% survival with heading on 29 April and full maturity on 9 June. The findings provide preliminary evidence for further breeding evaluation; replicated and multi-year testing is required for definitive conclusions.
