where this is mentioned in the description.
For soft wheat, the duration of the vegetation period is a key biological indicator. Calculations utilize the sum of active temperatures above the biological zero (0 °C), and the BBCH scale is applied for the standardization of developmental phases, allowing for precise determination of tillering, stem elongation, heading, and ripening stages.
Typical values depend on the crop form: for spring soft wheat, the period ranges from 80–120 days, and for winter wheat — 180–320 days, including the winter dormancy period. Cultivars are classified into maturity groups based on the time taken to reach full maturity, which allows farmers to adapt sowings to the climatic conditions of the region.
The duration of the vegetation period directly impacts productivity and agrotechnology. Earlier cultivars are able to avoid drought, while cultivars with a long period provide higher potential for biomass accumulation under favorable conditions; however, developmental timelines may vary depending on the year's meteorological conditions, preceding crops, and background agricultural practices.
