Variety traits

Cold tolerance — soft wheat

Triticum aestivum L.

Cold tolerance in soft wheat is a component of overall winter hardiness and reflects the ability of plants to withstand critical temperatures while maintaining productive tillering and viability in the crown node.

In the reference 7 varieties crop Bread wheat, where this is mentioned in the description.

For winter soft wheat, critical temperatures in the crown node zone are considered to be -17…-19°C in the absence of snow cover and down to -25°C with snow protection. A decrease in this indicator leads to thinning of crops, a reduction in grain filling per ear, and the need for reseeding affected areas.

Assessment of variety resistance is conducted through field observations of plant stand density after winter, analysis of soil monoliths, laboratory freezing tests, and biochemical markers. The level of cold tolerance determines the ecological plasticity of a variety, influencing the choice of optimal sowing dates and seeding depth to ensure proper plant hardening in autumn.
