Variety traits

Maturity group — onion

Allium cepa L. var. cepa

Classification of onion varieties based on the duration of the growing season from emergence to mass leaf lodging, determining harvest timing, storage potential, and yield potential.

In the reference 288 varieties crop Onion, where this is mentioned in the description.

The maturity group of onions is measured by the number of days from full emergence to harvest maturity. Key visual indicators of harvest readiness include mass lodging of leaves in 65–85% of plants, a change in leaf color, and the onset of neck drying.

Onion varieties are categorized into early-maturing with a growing season of up to 90–100 days, mid-maturing at 90–130 days, and late-maturing at 120 days or more. For winter varieties, the duration is significantly longer, ranging from 270–290 days, including the overwintering period.

Selecting the maturity group is critical for organizing a continuous production cycle and planning storage. Late-maturing varieties are generally characterized by better shelf life and higher yield potential, whereas early varieties are intended for immediate sale. The assortment must be selected taking into account photoperiodic adaptation to the day length at a specific latitude.
