Plutonus is a late intermediate day brown onion variety, renowned for its very long storability. The long storage potential enables growers to store bulbs for long periods, therefore providing an option to market bulbs over an extended period i.e., flexibility in the market period. High yield potential and exceptional bulb quality makes Plutonus suitable for storage and export markets. This variety has very strong blue, waxy leaves which consequently results in a high tolerance against general foliar diseases. Plutonus seeds are size graded and treated as standard.
