Rijk Zwaan develops new varieties for any period of the year. In our breeding work of leek we bear in mind the various preferences you find in every country, such as shaft length, leaf colour and green/white transition. That is the only way for growers to get good sales of their product. For a good presentation on the shelves we select on attractiveness of a product. For growers it is important as well that the leeks are easy to clean and that the crop stays healthy. Strong, flexible leaves minimise the risk of any damage. It goes without saying that preconditions are a good yield and uniformity.
