Evaluating genotype-specific responses in bread wheat (Triticum aestivum) to late-spring frost conditions.

Genotype Triticum aestivum shows significant variation in response to late-spring frost, with Superhead being more adaptable and Roshan more sensitive, affecting yield outcomes.

• Why it matters: Understanding genotype-specific responses to frost stress is crucial for breeding resilient wheat varieties amid climate variability and late-spring frost risks.
• What they did: Researchers conducted a factorial experiment with three wheat genotypes, three growth stages, and three frost durations, analyzing physiological and yield traits across nine replications.
• The result: Findings reveal that physiological responses like proline and pigment levels are linked to frost tolerance, enabling targeted selection for improved cold resilience in wheat breeding programs.
