There is an enormous diversity in cucumbers. For instance, we develop cucumbers of varying lengths, colours and skins. From mini to long and from smooth to prickly. Rijk Zwaan varieties are characterised by a high production and a good shelf life. Other breeding traits depend very much on the user objectives and the growing area. For unheated polyhouses we look for harvest reliability by means of stable varieties with a high disease-resistance level. For other areas we select varieties that need as little energy as possible.
