Rapeseed Maturity Groups

Brassica napus L.

There are no standardized maturity groups for rapeseed; classification is based on the duration of the growing season from sowing to full maturity, measured in calendar days.

In the reference 328 varieties crop Rapeseed, where this is mentioned in the description.

The growing season for spring rapeseed varies from 80–90 to 120–130 days, while for winter rapeseed this figure is 250–265 days. The maturity index is determined by a combination of timelines, visual signs of pod browning and seed darkening, as well as the achievement of seed moisture levels of 10–13%.

Selecting a variety based on maturity timing is critical for planning the harvest campaign, reducing the risk of seed shattering, and adapting to local climatic conditions, including the threat of early autumn frosts. Growing season parameters also determine the timing of desiccation to standardize the ripening process.
