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

Genotype Triticum aestivum shows differential responses to late-spring frost, with Roshan being more sensitive and Superhead more adaptable, affecting yield traits.

• Why it matters: Understanding genotype-specific responses to late-spring frost is crucial for breeding resilient wheat varieties, as frost stress impacts reproductive success and yield stability.
• What they did: A factorial experiment with three wheat genotypes, three growth stages, and three frost durations was conducted, analyzing physiological and yield-related traits across nine replications.
• The result: Results indicate that physiological adjustments like proline accumulation and pigment levels are linked to stress tolerance but do not fully prevent yield losses, highlighting the importance of targeted genotype selection for cold resilience.
