Variety traits
Allium cepa L. var. aggregatum G. Don
Classification of shallot varieties based on the duration of the growing season from emergence to technical maturity, measured in days.
In the reference 35 varieties crop Shallot, where this is mentioned in the description.
The maturity group of shallots is determined by the number of days from seedling emergence to mass lodging of leaves and drying of the outer bulb scales. Early-maturing varieties reach technical maturity in 65–70 days, mid-maturing varieties in 70–80 days, and late-maturing varieties in a period exceeding 80–95 days.
This indicator is key for agronomic planning, allowing for the forecasting of calendar harvest dates and the selection of varieties suitable for the region's climatic conditions. Earliness determines the cultivation strategy, whether it is for producing marketable greens or for the formation of matured bulbs.
