where this is mentioned in the description.
Spring rapeseed is characterized by early-maturing varieties with a period of less than 80 days, mid-maturing — 90–110 days, and late-maturing — more than 110 days. Winter forms have a longer period: early-maturing up to 280 days, mid-maturing 280–310 days, and late-maturing more than 310 days, including the dormancy state during overwintering.
The duration of vegetation determines the choice of variety for a climatic zone, minimizing the risks of frost and crop failure to mature. Rapeseed is sensitive to daylight: its increase beyond 14 hours accelerates development, shortening the period of vegetative mass formation and affecting the overall productivity potential of the crop.
