Bulb — Onion
Allium cepa L. var. cepa
The main economically valuable organ of the onion, assessed by morphometric traits: size, weight, density, and shape index, which influence storage quality and suitability for mechanical harvesting.
In the reference 691 varieties crop Onion, where this is mentioned in the description.
For onions, the bulb is the primary object of evaluation, where the key parameters are size, determined by the maximum transverse diameter, and weight. Bulb shape is classified into six types — from flat to elongated — and is quantitatively expressed by the shape index, which represents the ratio of height to diameter.
Important agronomic characteristics include density and maturity, determined by the condition of the dry outer scales and the dried neck. Breeding also considers the trait of bulbil formation (nesting), where varieties that form a single bulb from the basal plate are preferred for commercial cultivation.
Technological quality indicators of the bulb include storability, determined by varietal traits, and dry matter content, which is important for industrial processing. Uniformity of bulbs in shape and weight is a critical factor for the efficiency of mechanical harvesting and grading.
