Variety traits

Bulb — Onion

Allium cepa L.

The onion bulb is the primary edible organ, evaluated based on morphometric traits (weight, shape, height-to-diameter index) and biological properties (number of growing points, divisibility, neck maturity).

In the reference 508 varieties crop Onion, where this is mentioned in the description.

To characterize an onion variety, one evaluates the weight (from 20 to 250 g or more), shape, color of the dry and succulent scales, as well as the number of bulbs formed from a single basal plate (divisibility). An important indicator is the thickness of the neck, the degree of closure of which after drying determines suitability for long-term storage.

The number of growing points, which expresses the number of buds on the basal plate, along with the number and density of dry scales, serves as a criterion for selecting cultivation and post-harvest processing technologies. Uniformity of bulbs in shape and size is a critical parameter for ensuring the efficiency of mechanical harvesting and subsequent product grading.
