where this is mentioned in the description.
The marketability of Welsh onion reflects the ability of the plants to maintain commercial suitability at the time of harvest, meeting quality standards. Key criteria include the condition of the leaves (scapes), absence of yellowed tips, signs of wilting, damage from pests and diseases, and the absence of premature bolting. In research and variety testing, this indicator is expressed through the yield of marketable produce in centners per hectare or as a percentage of the total harvest.
The marketability trait is a determining factor in the choice of variety and harvest timing, as overgrown plants lead to tissue coarsening and reduced leaf quality. The genetic potential of a variety is evaluated by the ability of the leaves to remain green and tender for an extended period. According to regulatory requirements, marketable Welsh onion produce must be clean and have a leaf length of at least 20 cm; varieties that retain succulence and market appearance during the period of reaching harvest maturity are considered to have high marketability.
